Sensor + Test 2018: CMOS image sensor chip ousts CCD devices
The NSI3000 CMOS image sensor chip from Newsight Imaging is designed for machine vision applications. It is available at distributor Unitronic. It uses 8 rows of 2048 pixels made up of 4 rows of 4 µm x 8µm pixels and 4 rows of 4µm by 4 µm pixels.
Binning of the large pixels provides high sensitivity while the small pixels can provide a fine signal with effective resolution of 8192 with low power dissipation and compact size.
The NSI3000 is designed for programmable high frame rate speeds, allowing better analysis and reaction to events.
The sensor is manufactured in CMOS technology with extremely high sensitivity pixels. This high sensitivity allows the sensor to replace more expensive CCD sensors in many applications.
Other features include multiple readout modes, double buffer mode for high frame rate, ambient light subtraction and integrated band gap reference.
The sensor is supported by the NSI3000B evaluation board.
