The IMX531 from Sony is a 20.35 MP Stacked CMOS Image Sensor (diagonal 17.5 mm or 1.1 type). It features a global shutter function using a back-illuminated pixel structure for industrial equipment applications. The global shutter function enables imaging without distorting moving objects. This sensor has a frame rate of 74 to 106 fps and a sensitivity of 2030 to 2571 digits. The proprietary back-illuminated pixel structure allows for a compact size of only 2.74μm square, but still maintaining pixel characteristics such as sensitivity and saturation signal level.
The IMX531’s readout frame rate is approximately 2.4 times the speed of conventional image sensors. This is due to the highly flexible wiring layout of the back-illuminated pixel structure, and the use of the Scalable Low Voltage Signaling with Embedded Clock (SLVS-EC) high-speed interface standard developed by Sony. This sensor is designed for high-end cameras using high-speed bandwidth. In addition to the standard model that supports 5G bps supplementing the expansion in the application of USB 3.0 and 5GigE, it also reduces the time needed for measurement and inspection processes for various applications, including inspection, image recognition, identification, and measurement.
