Claims (16)
- 1. einem Laser-Strahler,
- 2. einer Membran, die aus einem Material hergestellt ist, das zum Teil die Laser-Strahlen reflektiert und zum Teil durchlässt,
- 3. einem kleinen Laser-Licht-Reflektierenden Teil bzw. Spiegel, das in dem Raum auf der anderen Seite der Membran gegenüber dem Laser-Strahler angebracht ist und das die Laser-Strahlen, die durch die Membran angekommen sind, in Richtung Membran bzw. Foto-Sensor, der in den Raum, wo sich der Laser-Strahler befindet, reflektiert, besteht (Fig. 3).
- 1. a laser emitter,
- 2. a membrane made of a material that partly reflects and partly transmits the laser beams,
- 3. a small laser light-reflecting part or mirror which is attached in the space on the other side of the membrane opposite the laser emitter and which the laser beams which have arrived through the membrane in the direction of the membrane or Photo sensor, which reflects into the room where the laser emitter is located ( Fig. 3).
