The MT9T031 is a 3.15-megapixel CMOS image sensor manufactured by On Semi (Micron, Aptina). It delivers a 2048 × 1536 pixel array with a 3.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 8.192 mm diagonal with a 0.16875 aspect ratio, typical of the 1/2-inch optical class used in compact industrial cameras. With 3.2 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
