[0023] Example 1: Hadamard Transform Fluorescence Spectroscopic Microscopic Imager

[0024] Hadamard Transform Fluorescence Spectroscopic Microscopic Imager, the fluorescence imaging signal from the microscope is introduced into the spectral direct-reading Hadamard transform spectral imaging system. The light modulated by the template is focused by the cylindrical lens group at the entrance slit of the monochromator into an elongated rectangular light spot suitable for the size of the entrance slit. This spot is a clearly coded image of the sample, and is positioned exactly in the center of the entrance slit knife edge of the monochromator. After entering the monochromator, the grating splits the light, and the dispersed light beam is focused on the surface of the image-sensitive unit of the area array grayscale photodetector. The computer workstation regulates the Hadamard template for Hadamard coding, receives the signal of the area array grayscale photodetector, and finall...

Abstract

A spectrum direct-reading type adama transformation spectrum imaging system comprises a focusing lens assembly, an adama template, a cylindrical mirror lens assembly, a monochromator and a plane array photoelectric detector. A driving mechanism for driving the adama template is provided, the photoelectric detector is a plane array gray scale detector, and the cylindrical mirror lens assembly collimates and focuses coding optical signals of a future self-focusing lens assembly and is compressed into a lens assembly of light spots matching with the size of plane array gray scale detector. The spectrum direct-reading type adama transformation spectrum imaging system integrates adama transformation technology and spectrum direct-reading design to realize the capability of rapidly realizing spectrum data cube. The system has high system expansibility and compatibility and can be connected with other lenses and optical systems.

Description

technical field [0001] The invention relates to the field of spectral measurement technology and optical imaging technology, in particular to the design of a spectral direct reading type Hadamard transform spectral imaging system. Background technique [0002] Hadamard transform technology is a modulation technology similar to Fourier transform, which has the ability of multi-channel detection and imaging. Using this technique can significantly improve the signal-to-noise ratio. Although this technology has begun to be applied in the field of spectral analysis and microscopic imaging, the functions of the instruments applying this technology are relatively single, and the integration of spectral analysis and imaging capabilities is very poor. For example, patent ZL94107751.9 discloses a Hadamard transform low-resolution imaging system, which uses a 15×17 two-dimensional Hadamard template to obtain a microscopic image of 15×17 pixels. Patent 01106536.2 discloses a high-reso...
