MT3805SD

MT3805SD is a miniature optical Direct Time-of-Flight (dToF) sensor. The sensor integrates a 940nm Vertical-Cavity Surface-Emitting Laser (VCSEL), and is based on Single-Photon Avalanche Diode (SPAD), Time-to-Digital Converter (TDC), and histogram architecture. MT3805SD can measure distance between up to 1000mm at a high ranging speed up to 120Hz FPS (frame per second). Additionally, the precise ranging of an object is unaffected by its color, reflectance and texture of the object. The built-in histogram-based algorithm with cover glass calibration and compensation for smudges is implemented for high-reliability applications. Ambient light noise is minimized by using a narrow-band optical filter and built-in sunlight rejection algorithm. MT3805SD processes all data internally and provides distance information and confidence level values via its I²C interface.
