Product Introduction

BT008D is a CMOS-ToF depth image sensor designed for 3D depth sensing based on indirect Time of Flight (iToF) method with short pulse modulation (SPM). Brookman’s innovative multi-tap gating pixel structure and an optimized pixel operation for iToF with SPM achieve high speed and high SNR depth sensing without dynamic motion defects. A QVGA resolution, approximately 80,000 effective pixel points, can be reasonable and well-matched for fast post-processing. In addition, this sensor is equipped with on-chip 12-bit high speed analog to digital converter so that it gets a fast readout time with low temporal noise. MIPI CIS-2 and CCI are adopted to the sensor interface.
