Multidimensional full field optical calibrator

Abstract

The invention provides a multidimensional full field optical calibration device used for the hyperboloidal reflection mirror which includes collimated light source, a beam microscopy, an optical reference arm, an optical measurement and a receive device; the collimated light beam issued by the collimated light source collimator the beam irradiates into the beam microscopy, the beam microscopy divides the collimated light source into two parts, the reflection part is after reflected by the reflection mirror II and then permeated the beam microscopy to be a reference light; the transmission part is converged to part of mirror of the measured hyperboloidal reflection mirror by the convergence lens, the extension of the convergence light in the intersection of a focus of the hyperboloidal reflection mirror, after reflected by the measured hyperbolic reflection mirror, converge to a standard spherical reflection mirror, the extension of the light converges to the core of the spherical reflection mirror, after reflected by the spherical reflection mirror, returns along the original track, then reflected by the measured hyperboloidal reflection mirror and the convergence lens mirror and semi- reflection mirror, to be a test light; reference light and convergence light converge to the receive device. The device for the invention can measure the surface morphology and measurement parameters of the hyperboloidal reflection mirror which have different scales and high reflection.

Description

(1) Technical field [0001] The invention relates to an optical calibration system, in particular to a multi-dimensional full-field optical calibration system of a hyperboloid mirror. (2) Background technology [0002] Optical all-round vision technology has gained widespread attention at home and abroad in recent years, and its application fields include robot vision, fire point monitoring, shooting range monitoring, truck rear view, lunar rovers, Mars rovers, security protection and many other military and civilian fields. In the military, this system can be placed on the target ship to monitor the trajectory of incoming missiles. It can be applied to robots or tanks as a means of environmental observation. In the civilian field, it can be used as a rear observation system for box trucks, or as a security system for public places. The core component of monitoring and fire point monitoring in important places. The advantage of this technology is that one CCD lens can be use...

Problems solved by technology

[0005] The traditional surface measurement method requires the measured surface to have a certain diffuse reflection property, which does not meet the test requirements of the hyperboloid reflector; the test of the spherical reflector can use the Tieman-Green interferometer, but it is not suitable for the hyperboloid reflector; if For a mirror of a certain fixed size, there is also an aspheric lens (compensator) for full-field measurement of the mirror under test (references: Guo Peiji, Yu Jingchi, using the correction method to improve the accuracy of the compensator detection method, Optical Precision Process, Volume 14, Issue 2, Page 202-206, 2006), but this compensator detection method cannot be used as a test method for a series of hyperboloid mirrors, and the processing of the aspheric mirror (compensator) is also very difficult
