Embodiment Construction
[0011] exist figure 2 As shown, the target photocell of the laser communication receiver is equipped with a light-receiving cover. The shape of the light-receiving cover is close to a spherical shell, and the volume is hundreds of times that of the tiny photocell. The material is a semi-transparent material. Located in the light receiver cover.
[0012] Due to the large size of the photoreceptor, it is very easy and convenient to realize the laser beam homing. As long as the laser beam is roughly aligned with the photoreceptor, the signal transmission can be completed at any part of the front, side, and rear of the photoreceptor.
[0013] The implementation of this technology not only ensures the reliability of the laser communication experiment method, but also greatly improves the practicality of the laser communication.

The invention provides a technology for additionally arranging a light receiving cover on a laser communication experiment target photoelectric tube. The light receiving cover is similar to a spherical shell, the size of the light receiving cover is hundreds of the size of a miniature photoelectric tube, the light receiving cover is made of semi light transmitting material, and the photoelectric tube is located in the light receiving cover. Due to the fact that the size of the light receiving cover is large, laser beam seeking can be very easy and convenient to conduct only by roughly aligning laser beams with the light receiving cover, and signal transmission can be finished at any position of the front side, the lateral side and the rear side of the cover. By the implementation of the technology, reliability of a laser communication experiment means is guaranteed, and the practical degree of laser communication is greatly improved.
Description
technical field [0001] The invention relates to the technology of laser communication, and specifically refers to the technology of adding a light-receiving mask to the photoelectric tube of the laser communication experiment target. Background technique [0002] In order to explain and demonstrate laser communication to students or the public, various experimental machines for laser communication have been developed. The whole machine is composed of two parts: transmitter and receiver. Brief description of the working process: a signal-modulated strong laser beam is emitted from the laser emitting tube of the transmitter, and propagates through the atmosphere or other media. Once it hits the target photoelectric tube of the receiver, the photoelectric tube will excite The current that changes according to the signal, and then the tiny current is amplified and demodulated, and useful signals can be separated, thereby realizing laser communication. [0003] However, the fol...
