Ultra-wide spectrum laser bird repellent

Abstract

Disclosed is an ultra-broadband spectrum laser bird dispeller. The ultra-broadband spectrum laser bird dispeller comprises a laser device, an optical coupling system, a nonlinear optical material, an optical collimation system, an optical attenuator, an optical beam splitter, an optical focusing system, an optical collimation and beam expanding system, an optical mirror, an optical emergence window, a vertical mechanical rotating platform, a vertical mechanical rotating platform driving source, a horizontal mechanical rotating platform, a horizontal mechanical rotating platform driving source, a photoelectric receiver, a photoelectric control system and a remote control system. By the ultra-broadband spectrum laser bird dispeller, the problems of few bird dispelling species, poor bird adaptability of single-wavelength laser bird dispelling are solved effectively, and bird dispelling effect and bird dispelling efficiency are improved; application field and application range are expanded greatly, and the ultra-broadband spectrum laser bird dispeller can be used for dispelling other wildlife. The laser bird dispeller can be widely applied to places such as airports, orchards, forest farms, aquaculture farms, power stations, urban environmental protection areas and natural ecological preservation areas, and is of great significance to aviation safety, agriculture, fishery and forestry development, wildlife protection, ecological balance and the like.

Description

technical field [0001] The invention belongs to the technical field of laser bird repelling, and relates to the fields of bird vision, aviation ornithology, ecology, laser, nonlinear optics, optical waveguide theory and technology, electronics, automatic control and the like. It is suitable for bird repelling applications in airports, orchards, forest farms, aquaculture farms, power plants, urban environmental protection and ecological protection sites, etc. Background technique [0002] Due to the improvement of people's awareness of ecology and environmental protection, the number of various birds in the world is increasing, which seriously threatens the safe take-off and landing of aircraft, brings huge losses to agricultural production, horticultural production, and fish farming, and also affects wind power. The safety of power plants even affects urban environmental protection. At present, the methods of bird repelling mainly include voice bird repelling, wind force bi...

AI Technical Summary

Problems solved by technology

However, laser bird repellers currently use single-wavelength lasers such as 532nm, 520nm, 633nm or 650nm, and research by the Wildlife Research Center of the United States Department of Agriculture shows that single-wavelength lasers can only have a good repelling effect on certain types of birds. and found that light in the spectral range from ultraviolet to 750nm has repelling effects on different kinds of birds

Therefore, the scope of use of single-wavelength laser bird repellers has serious limitations
