WebThe time delay is proportional to twice the distance between the camera and the object (round trip). Therefore, the distance can be estimated as the depth d = (c × Δt)/2, where c is the speed of light. A ToF camera thus outputs 2D data as well as the required depth information. Figure 1. Time of flight measurement principle. WebAcuity’s most accurate and most resolute distance sensor employs a unique measuring principle, confocal chromatic sensing. Unlike our time-of-flight and triangulation sensors which use lasers, the CCS Prima Confocal sensors use a white light source to accurately measure the distance to surfaces. Some models are accurate to within 20 nanometers.
