Page 13: Figure 3. Camera Front With Beamsplitter And Fibers
IIT Camera System Manual The concept of the IIT Camera is to exploit the retro-reflective properties of the vehicle license plates. A retro-reflective surface returns the incoming light in the same direction it comes from. The IIT camera is equipped with a number of emitting infrared diodes that are positioned evenly across the camera lens. - Page 14 IIT Camera System Manual Vehicles are detected from both driving directions (front or rear shots). The system will only work if the license plate is moving through the retro-reflective sensitive region of the picture area. Other parts of the vehicle being retro-reflective can cause generation of triggers. These parts can be the tail light or stickers of different kinds.
