Embodiment Construction

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing function and circuit communication function.

[0029] It is to be understood that the terms "length", "width", "top", "bottom", "front"...

Abstract

The invention discloses a high-resolution spectral image rapid acquisition device and method. The device comprises an illumination light source, an objective lens, a spectroscope, a single-shot spectral image acquisition assembly, and a reference image acquisition assembly. The illumination light source is used for projecting illumination light onto the sample to be detected so that the sample tobe detected is amplified by the objective lens, the amplified light is divided into two parts of light by the spectroscope; one part of light enters the single-shot spectral image acquisition assemblyso as to acquire a low-resolution spectral cube of the sample to be detected, and the other part of the light enters the reference image acquisition assembly to acquire a high-resolution spectral cube. According to the invention, the high-resolution spectral image can be rapidly obtained, so that the process of applying the spectral image to medical diagnosis is accelerated.

Description

technical field [0001] The invention relates to the field of image technology, in particular to a device and method for quickly acquiring high-resolution spectral images. Background technique [0002] Hyperspectral images have two spatial dimensions and one spectral dimension, which can provide information about tissue physiology, morphology, and composition, and thus are widely used in disease diagnosis and image-guided surgery. Cells in a disease state have different structures or metabolic rates from those in a normal state, and thus have different fluorescence emission spectra. Therefore, fluorescence hyperspectral images have the ability to diagnose diseases in the early stages of diseases. [0003] At present, in the field of pathological imaging, spectral images and fluorescence spectral images are mostly obtained by point scanning spectroscopic method (pushbroom) and switching filter method (staring), but these two methods will cause huge time expenditure, and switch...
