Laser leading beacon optical system

Abstract

A laser leading beacon optical system disclosed by the present invention comprises an adjusting pedestal, a light source laser arranged on the adjusting pedestal, a light beam adjusting and shaping unit, a diaphragm, a projection optical system and a protection window. The light source laser emits a laser beam to pass the light beam adjusting and shaping unit, the diaphragm and the projection optical system, and finally the laser beam is emitted out from the protection window. According to the present invention, the red and green two fan-shaped light beams of high visibility, high transmissivity and high directivity are generated for the laser leading beacon system, the two light beams are located in a same plane, and the boundaries of the two light beams have some overlap, so that the marine navigators can be navigated on the severe weather conditions, such as the rain, the fog, etc.

Description

technical field [0001] The invention relates to a laser guide, in particular to a laser guide optical system. Background technique [0002] A new guide system with laser as the light source. The optical system is the technical core of the new guide. It is responsible for generating high-quality laser beams for the laser guide system. Good penetrating ability, high reliability, long service life and low energy consumption, especially in rain, fog and other poor visibility weather conditions, will produce a very good navigation aid effect. In addition, the laser is a monochromatic light with a color saturation of 1, which is clearly contrasted with the background light and easy to identify. [0003] Traditional navigation lights use LED light-emitting diodes as the main light source. Patent CN102980124A (LED beacon light based on wind-solar complementary integrated power supply mode) introduces an LED beacon light with wind-solar complementary power supply mode. The beacon ...

AI Technical Summary

Problems solved by technology

The implementation methods of the above-mentioned navigation lights all use LED light-emitting diodes as the main light source. The characteristics of the LED itself determine that it has a great deficiency in the quality of the navigation beam: first, when the wharf is operated at night, a large number of lighting facilities are put into use, and the guides set by the navigation mark department are surrounded by light. There are background lights all over, and the light intensity of the guide light is almost the same as that of the background light, making it difficult for drivers of ships entering and leaving the port at night to recognize the guide light

Secondly, it is even more difficult to identify navigation aids under severe weather conditions such as rain and fog, which brings great hidden dangers to navigation safety.
