Optical transmission device |
摘要 |
The optical transmission device comprises a transmitter which emits radiation vertically with respect to a covering surface. A reflection surface reflects a portion of the emitted radiation back onto an optically sensitive reception zone of a monitor receiver which is disposed on the same side as the transmitter. An intermediate body with a reflecting circumferential surface is disposed between the reflection surface and the reception zone. At least a portion of the reflected radiation passes from the circumferential surface to the reception zone, which significantly increases the yield of the reflected portion used for monitoring purposes.
