Efficient measuring system and method for transmittance of reflecting telescoping system

Abstract

The invention provides an efficient measuring system and method for transmittance of a reflecting telescoping system. An aligning system is disposed on an emergent light path of a light source system. A star point unit is disposed between the light source system and the aligning system and located on a focal plane of the light source system. A rotary light beam axis folding system is disposed on an emergent light path of the aligning system. The reflecting telescoping system to be measured is disposed on an emergent light path of the rotary light beam axis folding system. The output end of the reflecting telescoping system to be measured is connected with a spectrum collecting system. The method includes: spatially translating aligning light beams through the rotary light beam axis folding system and then transmitting the same into the spectrum collecting system. The measuring system bypasses the special structure, with spoke ribs, of a reflecting telescoping system secondary scope, transmittance can be measured in areas among the spoke ribs, and transmittance of the whole caliber range of the telescoping system can be comprehensively measured after circular rotation.

Description

technical field [0001] The invention belongs to the field of optical detection, and in particular relates to a measurement system and method for testing spectral transmittance for reflective telescopic systems (such as Cassegrain systems and RC systems). Background technique [0002] As people's curiosity about the microcosm and distant outer space is increasing day by day, optical imaging systems are also developing rapidly under the background of this strong demand. High-magnification electron microscope microscopes, large-caliber and long-focus astronomical telescopes, and even sub-aperture splicing large-caliber space telescopes for space have sprung up in front of the world. This prosperous and prosperous scene has made the global optical field excited uplifting. [0003] Nowadays, optical systems such as space-borne detection, space-borne surveying and mapping, and ground-to-space photoelectric theodolite mainly adopt the structure of reflective telescopic system due ...

AI Technical Summary

Problems solved by technology

However, reflecting telescopes are generally large and bulky, and are not suitable for moving back and forth, up, down, left, and right

The corresponding test collimator is also fixed, which is inconvenient to move and cannot meet the requirements of testing in different areas.
