Problems solved by technology

Therefore, combined with the imaging characteristics of each band, the infrared optical system working in a wide band can obtain sufficient and useful information, which can avoid the limitations of information acquisition by a single-band infrared system, and play an important role in target detection and recognition. The infrared optical system generally has the problem of narrow system working band, and it is urgent to provide a new optical system to solve this problem

Abstract

The invention provides a medium-short wave broadband infrared optical system and a remote sensing optical device, which adopt a cylindrical primary imaging system configuration. The optical system iscomposed of four spherical mirrors. All elements are arranged on the same optical axis. The optical system has the characteristics of wide working waveband, compact structure, high suitability, high imaging quality, and transfer function reaching or close to the diffraction limit and the like.

Description

technical field [0001] The invention relates to the field of optics, in particular to a medium-short-wave wide-band infrared optical system and remote sensing optical equipment. Background technique [0002] The infrared optical system has the advantages of good environmental adaptability, high concealment, and strong anti-interference ability, and is widely used in various fields such as military, medical, security, electric power, remote sensing and industry. , It also puts forward higher requirements for the design of infrared imaging system. [0003] Since the atmospheric window is distributed in the three bands of near-infrared of 0.75-2.5 μm, mid-wave infrared of 3-5 μm and long-wave infrared of 8-14 μm. The traditional infrared imaging system generally has a narrow working band, and the amount of information obtained is limited. Therefore, combined with the imaging characteristics of each band, the infrared optical system working in a wide band can obtain sufficient...
