Abstract

The invention discloses a Conoscopic lens array imaging system. Based on a characteristic that Conoscopic lens imaging sizes are relevant to visual angles and irrelevant to distance, an imaging targetspatial position information acquisition method is fully explained when an array design system is made of two Conoscopic lenses, four Conoscopic lenses and 16 Conoscopic lenses. The invention also discloses a Conoscopic lens array imaging system-based imaging target spatial position information acquisition method. An imaging target spatial position information principle and calculation method canbe obtained based on geometric operation via use of information such as distance between the lenses, imaging aberrations, imaging angles and the like; a method for obtaining imaging target spatial position information when the array design system is made of n2 Conoscopic lenses is further derived. Via the imaging target spatial position information acquisition method disclosed in the invention, good imaging effects can be ensured, and imaging target information can be obtained as much as possible.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a Conoscopic lens array imaging system and a method for acquiring spatial position information of an imaging target. Background technique [0002] The Conoscope was invented by W.L. BOND in 1944 and is mainly used to observe and analyze the characteristics of crystal materials. The lenses used in Conoscope are called Conoscopic lenses. Its imaging is opposite to the characteristics of pinhole imaging. The pinhole imaging is an inverted image, and the size of the image is related to the distance, while the Conoscopic lens is a positive image, and the size of the image has nothing to do with the distance. [0003] A single Conoscopic lens can be used for quick testing of viewing angles, and can also be used for brightness, chromaticity, and contrast tests related to display angles; in addition, it can also be used for display and scattering characteristics tests of various...
