Wavelength tuning light bird dispeller

Abstract

Disclosed is a wavelength tuning light bird dispeller which comprises a light source, a light-source driving source, a wavelength tuning control system, an optical focusing system, an optical collimation and beam expanding system, a light beam scanning system, a photoelectric control system, a remote control system and a two-dimensional mechanical rotating platform. The light source can output in a tuning manner with a single wavelength, or output in a tuning manner with several fixed wavelengths or output in a tuning manner with wavelength in a certain spectrum band, serious problems of few bird dispelling species, poor single wavelength adaptability of birds and the like of existing single-wavelength laser bird dispellers are solved, bird dispelling species are widened greatly, and bird dispelling effect and bird dispelling efficiency are improved greatly, thus the wavelength tuning light 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, can promote aviation safety, agriculture, fishery and forestry development, bird preservation, ecological balance and the like greatly, and can bring immeasurable economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of light-driven birds, and relates to the fields of bird vision, photoecology, aviation ornithology, laser, optics, nonlinear optics, mechanical technology, automatic control and the like. It is suitable for repelling birds in airports, orchards, forest farms, aquaculture farms, power plants, urban environmental protection, and natural ecological protection areas. Background technique [0002] Airfield bird strike accidents occur frequently, accounting for 41% of aviation flight accidents, and have been designated as "A" aviation disasters by the International Aviation Federation; Bring huge losses; birds also affect the safe operation of power plants, environmental protection and service life of large buildings, etc.; birds even affect the city's environmental protection. Therefore, how to reduce bird damage has become a worldwide problem. At present, the main methods of repelling birds are: sound repelli...

AI Technical Summary

Problems solved by technology

However, laser bird repellers currently use single-wavelength lasers (such as 532nm, 520nm, 633nm or 650nm), and the visual wavelength range of birds is 300-750nm. Different birds have different light-sensitive wavelengths. Single-wavelength light It can only have a repelling effect on a limited number of birds, and birds are easy to adapt to a single wavelength of light. With the improvement of people's awareness of environmental protection and the emphasis on ecological balance, the number and types of birds also increase

In China alone, there are more than 2,500 species of birds, and more than 150 species of birds at airports. Therefore, the bird repelling range of a single-wavelength laser bird repellent is very limited.
