With the application of optical systems in conferences,robots,computer vision imaging,and virtual reality.The demand for the ultra large field of view and the compact optical system is getting higher and higher,and the belt type panoramic optical system is born.Firstly,the imaging principle and characteristics of the girdle panoramic optical system are introduced.Based on the plane cylindrical projection method,the ring type panoramic optical system with different head units is analyzed and designed.The three bonding head unit and a relay lens group forms,designs a panoramic panoramic annular optical system is designed firstly,choose the central head unit diaphragm position;ensure wide field light through the panoramic head unit after the exit for the parallel light,the lens group made head unit the virtual image imaging detector on again.The design results require that the focal length of the system is-1.75 mm,and the number of F is 2.16,the field of view is()36095~40°×°±°±,the working wavelength of the lens is 486nm—656nm,The total length of the final system is 12 mm,meetting the design requirements of less than 20 mm.The system design of miniaturization is realized.The modulation transfer function value of each field of view close to the diffraction limit when the spatial frequency is 227 lp/mm,the system has good imaging quality and meets the application requirements.Finally,the design results are analyzed and suppressed by the stray light,and the design of the system is completed.
