Large field-of-view optical system detecting device and detecting method

Abstract

The invention provides a large field-of-view optical system detecting device and detecting method, thereby solving problems that the existing detecting device can only detect the imaging quality of the central field of view of the optical system and thus the detection range is limited and the accuracy is low. The detecting device comprises a circular arc guide rail, a self-collimating collimator and at least one collimator. The self-collimating collimator is disposed outside the circular arc guide rail; and a first two-dimensional adjustment platform is disposed at the bottom of the self-collimating collimator. The at least one collimator is arranged on the circular arc guide rail in a sliding manner by a second two-dimensional adjustment platform; and the range of the field of view can beadjusted based on needs to carry out detection of the large field of view. The optical axes of parallel beams emitted by the self-collimating collimator and the at least one collimator are located onthe same horizontal plane and are intersected at the circle center of the circular arc guide rail. Therefore, the detection of the imaging quality of the large field of view of the optical system isrealized; and the operation becomes simple and the detection precision is high.

Description

technical field [0001] The invention belongs to the optical system detection technology, and relates to a large-field optical system detection device and a detection method. Background technique [0002] With the increasing application of optical systems, the demand for optical system performance testing and evaluation is also increasing, especially for infrared optical systems. The field of view of the optical system will affect the operating distance and accuracy of the system. The large field of view optical system can obtain more information and improve the efficiency of use, which is one of the current development directions of the optical system; and with the development of the current infrared focal plane technology , both linear array and area array infrared focal plane devices are becoming larger and larger, so there is an urgent need for infrared optical systems with large fields of view to match them. [0003] Due to some special application environments, the ima...
