Time-of-Flight sensor with 940nm integrated IR VCSEL in a 2.2mm x 3.6mm x 1.0mm optical module 1.8V I²C

特点

  • Direct ToF technology with high sensitivity SPAD detection
  • Fast Time-to-Digital Converter (TDC) architecture
  • Sub-nanosecond light pulse
  • 20 – 2500mm distance sensing @ 30Hz
  • On-chip histogram processing
  • 940nm VCSEL Class 1 Eye Safety
  • High performance on-chip sunlight rejection filter and algorithm
  • Industry’s smallest modular OLGA 2.2 x 3.6 x 1.0 mm package

优势

  • Delivers high SNR, wide dynamic range and no multi-path reflections
  • Enables dark and sunlight environment distance measurement within ±5%
  • Provides best-in-class resolution ranging mode detection sensing
  • Enables accurate distance measurements
  • Provides high accuracy, greater distance between cover glass, dynamic cover glass calibration, dirt or smudge removal and crosstalk compensation
  • Eye-safety circuitry stops VCSEL driver if VCSEL fault occurs
  • Optical filters with algorithm support enables high ambient light resilience
  • Reduce board space requirements, enables low-profile system designs in restricted space Industrial Designs
