ToF is short for Time of Flight.
It measures the time it takes to leave and reflect a light from an object to the sensor.
LiDAR is short for Light Detection and Ranging.
Actually ToF and LiDAR are sometimes misunderstood as the same thing, otherwise really similar technology. While LiDAR uses a laser or a pulsed laser to measure the room depth, ToF often refers to the technology non-including LiDAR. However, eventually both technologies are used to measure the distance and also 3D mappings, for Automotive, mobile sensor for instance, iPhones, Xperia, Samsung mobiles etc… Almost every electronic devices used in our life will may have ToF sensors in the future.
Regarding ToF /LiDAR evaluation system
Our ToF/LiDAR system helps to improve and develop these sensor technologies, also good for testing sensors to confirm their qualities.
ToF/LiDAR system is composed with NIR light sources, a chart stage, an electric motored rail and a darkroom. Normally 850nm or 940nm is the NIR wavelength used for ToF sensors. NIR is included in sunlight, so ambient lights might disturb a measurement when ToF technologies are used outdoor, in environments with ambient lights. In order to test it, it needs NIR light sources, NIR illuminations.
