Problems solved by technology

[0004] (1) The 224 position of the dichroic mirror cannot arrange the internal fixation optical path, and the position of the internal fixation optical path needs to be moved back to the 204 position, which increases the size of the device to a certain extent
[0005] (2) For the transmitted light path, the dichroic mirror will cause the offset of the optical axis, and it has different offsets for light with different incident angles. This offset will bring about a decline in optical performance and affect large-field imaging especially serious
[0006] (3) The distance b

Abstract

The invention relates to the field of imaging systems, in particular to a light splitting assembly and an imaging system. One aspect of the invention discloses the light splitting assembly, the light splitting assembly is of a polyhedral structure, and at least two adjacent surfaces in the polyhedral structure are of non-planar structures. According to the light splitting structure, light from different directions or different systems can be separated, the situation that the distance between a spectroscope and an eyepiece is too long or too small due to the fact that the spectroscope is arranged in a traditional light path system is avoided, the size of equipment is reduced, and light weight and miniaturization are facilitated.

Description

technical field [0001] The invention relates to the field of imaging systems, in particular to a spectroscopic component and an imaging system. Background technique [0002] Optical coherence tomography (OCT) is a three-dimensional tomographic imaging technology that can detect reflection or scattering signals at different depths in biological tissues, and has the advantages of non-contact, high resolution, and high speed. Since the invention of OCT technology, it has developed from the early time-domain OCT to the latest frequency-domain OCT, in which the frequency-domain system is divided into spectral domain OCT and frequency-sweeping OCT. The advantages in signal-to-noise ratio and imaging speed make frequency-domain OCT more widely used and recognized. [0003] Among them, in the prior art patent CN105011900A, it is disclosed that the LSO light and the OCT light 224 dichroic mirror position are combined, and then enter the human eye through the eyepiece 207, and after ...
