One pass instead of two—energy and structure in a single measurement
From the intersection of fundamental research and industrial engineering, Sony has unveiled a sensor that allows machines to see the invisible with unprecedented clarity and speed. The IMX711 X-ray CMOS sensor, born from a collaboration between Sony and Japan's RIKEN institute, captures 26,100 frames per second while suppressing the electronic noise that has long obscured faint signals — a pairing that allows a single chip to do what once required multiple instruments. In the long arc of human efforts to peer inside matter without disturbing it, this device represents a quiet but meaningful step: the collapsing of sequential, laborious inspection into a single, simultaneous act of seeing.
- Industrial inspection has long been constrained by a fundamental tradeoff — speed or precision, density or elemental detail — forcing manufacturers into slow, multi-step measurement workflows.
- The IMX711 breaks that constraint by detecting X-ray photon energy directly and simultaneously across a wide brightness range, collapsing what were once separate measurements onto a single chip.
- Noise suppression engineered to 34 e-rms means even the faintest X-ray signals survive the journey from object to data, making the sensor viable for low-flux scientific and industrial environments alike.
- Battery production lines and semiconductor fabs stand to gain the most immediately, as the sensor's 26,100 fps capture rate keeps pace with fast-moving manufacturing processes without sacrificing defect-catching precision.
- Sony is advancing toward mass production through its semiconductor solutions division, translating a RIKEN laboratory invention into a commercially scalable tool ready for integration across industries.
Sony has announced the IMX711, a direct conversion X-ray CMOS image sensor that captures at 26,100 frames per second — the fastest in its class — developed in collaboration with RIKEN, Japan's leading research institute. The sensor's speed stems from proprietary circuit design that prevents the charge buildup that typically degrades accuracy, while noise suppression engineered to 34 e-rms keeps faint signals visible even in low-flux conditions.
What sets the IMX711 apart is its ability to consolidate what has traditionally required multiple measurements into a single pass. Rather than forcing operators to preset detection thresholds, the sensor reads the full X-ray energy spectrum and outputs signals proportional to photon energy — enabling simultaneous measurement of elemental composition, crystal structure, and material density on one chip. This flexibility dissolves the rigid operating modes that have long constrained conventional X-ray inspection systems.
The practical reach of this capability is broad. In battery manufacturing, earlier detection of internal defects could reduce waste and improve yield. In semiconductor fabrication, it could accelerate quality control at a level of precision where minute structural variations carry real consequences. In research settings — materials science, structural biology, physics — the ability to gather multiple data types in a single scan could replace workflows that currently demand sequential instruments or repeated measurements.
Sony has published full specifications and is moving toward mass production through its semiconductor solutions division. The IMX711's journey from a pixel architecture conceived by RIKEN scientist Takaki Hatsui to a commercially scalable product illustrates a pattern increasingly central to advanced technology: fundamental research becomes transformative only when paired with the manufacturing capacity to produce it at scale.
Sony has built a camera that sees X-rays faster than anything else in its class. The company announced the IMX711, a direct conversion X-ray CMOS image sensor that captures at 26,100 frames per second—a speed achieved through proprietary circuit design that prevents the charge buildup that typically degrades accuracy in these devices. The sensor was developed in collaboration with RIKEN, Japan's premier research institute, building on pixel architecture invented by RIKEN scientist Takaki Hatsui and refined through Sony's manufacturing and engineering expertise.
What makes this sensor unusual is what it can do in a single pass. Most X-ray inspection systems require multiple measurements to gather different kinds of information about an object—its density, its elemental composition, its structural properties. The IMX711 collapses that workflow. It detects X-rays directly and outputs signals proportional to their energy, meaning it can measure both the total energy absorbed across a wide range of brightness levels and the energy signature of individual photons simultaneously. This dual capability sits on one chip, something conventional sensors have struggled to achieve.
The technical foundation rests on noise reduction. Random noise is the enemy of faint signal detection, and charge-integrating sensors are particularly vulnerable to it. Sony engineered the IMX711 to suppress noise to 34 e-rms, low enough that even weak X-ray signals remain visible and measurable rather than buried in electronic hum. Combined with the high frame rate, this means the sensor can inspect fast-moving objects—batteries rolling off a production line, semiconductor wafers in process—without sacrificing the precision needed to catch defects.
Energy resolution is the other pillar. The sensor acquires photon energy information without requiring operators to set detection thresholds beforehand, a constraint that has forced traditional systems into rigid operating modes. Instead, the IMX711 reads the full energy spectrum and lets analysts extract specific data afterward. This flexibility opens applications that previously demanded sequential measurements: distinguishing elements by their X-ray signatures, mapping elemental distribution across a two-dimensional surface, analyzing crystal structure and composition in the same inspection cycle.
The practical implications ripple across manufacturing and research. In battery production, faster, more precise inspection could catch internal defects earlier and reduce scrap. In semiconductor fabs, the sensor could accelerate quality control on advanced chips where minute structural variations matter. In scientific settings—materials research, structural biology, physics labs—the ability to gather multiple types of information in one measurement could streamline experiments that currently require multiple instruments or repeated scans.
Sony is moving toward mass production, with the sensor available through its semiconductor solutions division. The company has published full specifications on its website, signaling readiness for integration into commercial inspection systems. The collaboration with RIKEN underscores how cutting-edge sensor technology now emerges from the intersection of fundamental research and manufacturing scale—an invention from a research lab becomes viable only when a company can actually make millions of them.

La Conversación del Hearth Otra perspectiva de la historia
Why does frame rate matter so much for X-ray inspection? Isn't one clear image enough?
Speed matters because real manufacturing doesn't stop. Batteries move on conveyor belts, wafers flow through production lines. If your sensor can only capture a few images per second, you either slow down the line or miss defects. At 26,100 frames per second, you can inspect at production speed without compromise.
And the noise reduction—why is that the hard part?
Because you're trying to hear a whisper in a noisy room. X-rays are particles, and when they hit the sensor, they create tiny electrical signals. Random electronic noise can drown out those signals, especially when the X-ray flux is low. Sony had to redesign the circuit itself to keep that noise down to 34 e-rms. It's not a software fix; it's physics.
The energy resolution piece—that sounds like it's doing the work of multiple machines.
Exactly. Traditionally, if you wanted to know both how much energy hit a pixel and what kind of energy it was, you'd need two different measurements or two different systems. This sensor does both at once. You get the total integrated energy for brightness and contrast, and you get the individual photon energies for elemental identification. One pass instead of two.
Who actually uses this? Is this for hospitals, or factories, or labs?
All three, potentially. Battery makers and chip fabs are the obvious near-term customers—they need speed and precision. But researchers studying materials, crystal structures, or even biological samples could use it too. Anywhere X-ray inspection happens, this sensor could make it faster or more informative or both.
Why did Sony need RIKEN to build this?
The pixel architecture itself came from RIKEN research—that's the fundamental innovation. But turning a research concept into something you can manufacture at scale, in volume, with consistent quality, is a different problem entirely. That's where Sony's expertise in semiconductor fabrication and packaging comes in. Neither could have done it alone.
