Results forMT3801

MT3801 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. MT3801 is capable of achieving a distance measurement of 4000mm, a high ranging speed up to 120Hz. In addition, the precise ranging of an object is irrespective to color, reflectivity and texture of the object. A built-in histogram-based algorithm with cover glass calibration and compensation for smudges is implanted for high reliability operations. Ambient light noise is minimized due to narrow band optical filter and built-in sunlight rejection algorithm, making the chip available to outdoor sunlight environment for distance measurement. MT3801 processes all data internally and provides distance information and confidence values via its I²C interface.
