摘要：The information transmission system employs a light source (LG) providing a modulated light beam, received by a photosensitive layer (S) carried by a detector plate (P). The latter is attached to a holder (H) which incorporates a photodetector (D) at one edge of the plate (P) receiving the light propagated in all directions through the photosensitive layer (S). The photodetector (D) is pref. coupled to a reception circuit (E) providing at least one output information signal (a..e). Pref. the photosensitive layer (S) is attached to the plate (P) via an adhesive. It comprises a polycarbonate with a fluorescent colour component. USE - For operating garage door servo mechanism by remote control.
