NSI3100 is an advanced CMOS (Complementary Metal Oxide Semiconductor) image sensor chip for LiDAR (Light Detection and Ranging) applications used in ADAS (Advanced Driver Assistance Systems) and in autonomous vehicles.
The sensor is optimized for Newsight’s eTOF (Enhanced Time-of-Flight), which bridges the gap between short-distance iTOF and the 200-meter distance requirement of the automotive industry by extending the dynamic range while retaining high accuracy.
The NSI3100 sensor offers extremely high sensitivity pixels, enabling the replacement of expensive CCD (charge-coupled device) sensors in many applications.
The NSI3100 is designed for programmable high frame rate speeds, allowing better analysis and reaction to events.
NSI3100 is specifically designed for LiDAR applications, using 8 rows of 2048 pixels made of 4 rows of 4µm x 8µm pixels and 4 rows of 4µm x 4µm pixels. The large pixels provide high sensitivity while the small pixels can provide a fine signal with effective resolution of 8192 with low power dissipation and compact size.
