TOF Ranging Sensors
Broadcom 1D/3D-TOF ranging sensors
Time-of-Flight (ToF) sensors are optical sensors that measure the time it takes for a light signal to travel from the sensor to an object and back. They detect the distance and surface information of objects in their field of view.
Broadcom’s AFBR-S50-series lidar-sensors are used for high speed and high accuracy distance and motion measurements. These modules include highly sensitive 32 pixels APD detectors with various optics and laser configurations. With frame rates up to 3 kHz the AFBR-S50-sensors are fast tools to be used in robotics, autonomous mobile vehicles, drones and automation instruments. They cover distances from ~0.01 to 100m and a field-of-view from ~0.4°x0.4° up to 12° x 6°. The Broadcom sensors operate even under sunlight (100kLux) conditions. Easy system integration is given by a very compact size of approx. 12 x 8 x 8 mm, a simple 5V voltage supply and an integrated clock source. Data transfer is done via SPI.
