Optical velocity

WebA monochromatic electromagnetic wave propagates through an optical material. Snapshots of the electric field distribution are shown at two different times. The phase velocity describes the speed of the crests of the wave. The distance traveled by a crest in the time interval t 2 –t 1 is denoted by ΔZ. WebJan 1, 2001 · 4. -. Vehicle optical sensor. This chapter introduces three vehicle-installed optical sensor models—namely, laser radar, ground speed sensor, and ground view sensor (GVS), which function as driving support system for a vehicle and detect the road environment. GVS can distinguish road surface conditions by using an optical spatial filter.
