Title:
LARGE FIELD OF VIEW ENERGY DETECTION OPTICAL SYSTEM BASED ON CONCENTRIC SPHERICAL LENS
Document Type and Number:
WIPO Patent Application WO/2023/000886
Kind Code:
A1
Abstract:
A large field of view energy detection optical system based on a concentric spherical lens, comprising an asymmetric concentric spherical lens (1), a bending optical fiber panel (9), and a detector (10) which are sequentially arranged along a light incidence direction. The asymmetric concentric spherical lens (1) is composed of six lenses; the bending optical fiber panel (9) has a curved input surface having the same curvature as that of an image surface (8) of the asymmetric concentric spherical lens, and is provided at the image surface (8); an output surface of the bending optical fiber panel (9) is a plane; the detector is a planar detector, and is coupled to an output surface of the bending optical fiber panel (9); incident light passes through the asymmetric concentric spherical lens (1) and is then imaged on the image surface (8) thereof; and the light enters the input surface of the bending optical fiber panel (9), and finally passes through the output surface of the bending optical fiber panel (9) and is then imaged on the planar detector. The optical system has the advantages of being large in field of view, uniform in size of full field of view defocused spots, good in roundness, small in magnification chromatic aberration, and small in distortion and having energy close to Gaussian distribution, can increase the number of average stars in the field of view, and improves the measurement accuracy of a star sensor and the star map recognition success rate.
