Technical Field

Background

At present, a common signal positioning device usually needs to utilize the signal effect of flame, smoke and sound generated by fuming combustion to carry out identification, positioning, communication and communication. The smoke signal can only be effectively identified in the areas with wide view and high visibility in the daytime, and the smoke signal is easily influenced by severe environmental conditions such as strong wind and the like in the continuous emission process of the smoke signal, so that the accurate positioning cannot be realized. In the flash signal emission process, the emitted signal is mostly located in a visible light wave band, so that the signal can be easily captured by the unit detection of the non-friend target. Electronic signals generally need to depend on a huge power supply system as an energy source, and cannot adapt to rapidly changing field use environments. Because the laser has strong directionality and high brightness, the laser pointing direction is not influenced by strong wind and the like, and the positioning precision is not influenced by factors such as night, narrow visual field, low visibility and the like. The laser spectral line width is narrow, and the invisible area can be covered, so that the specific positioning laser spectral line can be appointed with the friend party, and the non-friend target single-position detection and capture can be avoided. Meanwhile, the smoke and fire pump laser technology is a non-electric light source pump solid laser system, and is very suitable for being used in the field environment due to the characteristics of no need of power supply equipment, compact structure, convenience in carrying and the like. However, the existing smoke and fire pump laser burns violently by means of chemical oxidation reaction, the burning time is very short, the reacted medicinal powder is easy to attach to the laser reflection cavity, the reflectivity is greatly reduced, and the cavity is cleaned and filled with the medicinal powder when the smoke and fire pump laser is used again, so that the output of single-pulse laser can be realized usually. In the maneuvering process of the field detection device, accurate positioning is difficult to realize by means of single laser signals.
