Research And Analysis Of The Aerial Camera Optical Machine’s Key Technology

Aerial cameras have made major contributions to the development of resource telemetry technology and autonomous agriculture in recent years.The design of optical systems is an important component of the development process for airborne cameras,and it has an impact on subsequent structural design,camera assembly,and debugging.This article focuses on the design and research of an anti-telephoto optical system using an aspherical surface.The image system of the camera is created and optimized using Zemax optical design software,as well as non-thermal design and tolerance analysis.On this basis,design and analysis of the camera structure.The following is the primary research content:1)The existing classical optical system structure is studied,and the initial optical system structure is chosen.Based on this,the parameters of the optical system’s initial structure are calculated,the optical system’s initial structure is determined,the optical performance of the initial structure is analyzed,and the effect of adding optical elements on the optical system’s imaging quality is verified.2)Studying aberration theory helps with optical system optimization,which is essentially aberration correction.The optical system is optimized and verified to meet the imaging requirements by figuring out how many optimization operations need to be performed.The aspherical mirror is used because it is lightweight and because the aspherical surface can effectively correct system aberration.The aspheric anti-telephoto optical system is consequently best suited to satisfy the imaging requirements.To confirm the excellent optical performance of the aspherical mirror,an optical system with a global surface is compared with the aspherical optical system.3)Perform non-thermal design research and analysis,and non-thermal design for antilong-range optical systems based on aspherical surfaces.The system is designed without heat to ensure good imaging at-20 °C,20 °C,and 60 °C by dividing the temperature of-20 to 60 °C into three configurations,replacing the curvature radius setting variables,and glass parameter settings under multiple configurations,and solving them.This ensures the imaging quality of the optical system in various temperature environments.4)Analyze the errors that affect optical system imaging and introduce tolerance analysis methodologies.The tolerance values of the optical system are defined and examined based on sensitivity analysis to guarantee that the influence of the adjustment procedure on the imaging quality of the optical system is within a controllable range.5)The camera’s mechanical structure is designed and analyzed.Firstly,the model of the camera’s mechanical structure is established,and on this basis,ANSYS software is used to perform static analysis,modal analysis,frequency response analysis,and then verify the rationality of its mechanical structure.
