Research On Visual Optics Of Dove And Turtles

Birds are human friends.As the protection of birds is getting better and better,the living environment of birds is getting better and better,which makes the number of birds increasing.As a result,a growing number of birds have brought many hazards to the orchards,ponds,airports and other areas,affecting the production and life of human beings.Thus,it is imminent to drive the birds.With the seriousness of bird damage,various bird repellent methods are produced.Many bird hunting methods have killed birds,including birds protected in many countries.The laser drive bird is also one of the ways to drive the birds.In order to study the mechanism of the laser displacing birds,this paper chooses the dove and the turtles as the research object,and studies their visual sensitivity.The main contents of this paper are as follows:(1)to study the visual optics of birds in foreign countries mainly at home and abroad,analyze the history and present situation synthetically,and choose suitable research objects according to the needs of the research on the mechanism of the laser repelling birds.Dove is very popular in this field.Turtles and dove are very similar.Therefore,dove and turtles are identified as the objects of visual optics.(2)according to the need,we carried out the theoretical research of bird's visual optics,selected the bird species studied,and thought about the research of birds' color vision and so on.In this paper,the theory of color perception and spectral sensitivity is explained mainly in the theory part of this paper.The color sense is mainly the introduction of three colors and antagonism,and the birds are four colors.Then,the influence of wavelength on vision is introduced,and the theory of spectral sensitivity is introduced.(3)a quantitative experimental study of the visual sensitivity of dove and turtles on light is carried out,and the comparison between the experiment of dove and the experimental results of foreign countries shows that the experiment is feasible,which makes a paving for the experimental study of the turtles.It is finally confirmed that the yellow green band near 580nm is a sensitive band of dove turtles.In order to further summarize the results,we can expand the experiment.More than 1.experiments on several kinds of birds.2.on the basis of the above research,the research on the mechanism of the laser repelling bird can be carried out well,and the problems such as the lack of laser repellent,the lack of industry standards and the national standards are solved,and the harm of birds is eliminated..
