Common image face multi-optical spectrum imaging technology

Abstract

The invention discloses a common image plane and multi-spectrum imaging technique. A fixing ring is arranged at the front end of an imaging sensor, and a band-pass filter with different checking frequencies is arranged in the ring. An imaging coupling unit formed by an aspheric imaging lens and an imaging coupler is correspondingly arranged at the output end of each wave filter. A glass-covering face is arranged on the receiving face of the imaging sensor, and an image plane coupler is arranged on the glass-covering face. An image transmission optical path is arranged between the imaging coupler and the image plane coupler. The front terminal of each image transmission optical path is connected with the imaging coupling unit so as to couple the images formed by the aspheric imaging lens to the receiving port of the image transmission optical path. The back terminal of each image transmission optical path is connected with the image plane coupler to image the information transmitted in the path onto the image plane corresponding to the imaging sensor with the same frame. The invention can realize synchronous common image plane imaging for different spectrum sections in the same observing scene at the same moment so as to realize the microminiaturization of the system structure on the basis of guaranteeing a high real-time of the common image plane multi-spectrum imaging.

Description

technical field [0001] The invention belongs to optical imaging technology, and in particular relates to a technology of multi-spectral section imaging and common image plane multi-spectral imaging. technical background [0002] In the field of multi-spectral detection, it is necessary to analyze and process the image data of multiple frames of different spectral segments. To obtain multiple frames of image information in different spectral segments, there are two existing technologies: one is to use multiple imaging sensors and configure different filters respectively; the other is to place a dial with multiple filters on the front end, The back-end uses a single imaging sensor, and is controlled by a timing drive circuit to select the spectral segment information of different channels in the front-end. Although these two methods are relatively mature, they have obvious shortcomings. Mainly reflected in: Although the first method has better real-time performance, the over...

Problems solved by technology

Although these two methods are relatively mature, they have obvious shortcomings.

Mainly reflected in: Although the first method has better real-time performance, the overall structure is too large due to the need for multiple imaging sensors, and it cannot be miniaturized; the second method requires additional mechanical dials and drivers, and only It can collect sequential images, but cannot collect image information of the same observed scene in different spectral segments at the same time, and the real-time performance is poor
