Problems solved by technology

[0005] The purpose of the present invention is to use the microlens array to realize simultaneous light splitting in two-dimensional space on the basis of the dispersion-type spectroscopic principle, and obtain the spectral distribution image of the two-dimensional space of the sample in one imaging, thereby overcoming the need to line-by-line in the prior art Or point-by-point scanning to obtain the shortcoming of two-dimensional spatial spectral resolution, and thereby solve the problem of low sampling efficiency in the prior art
Two-dimensional spatial sample image discrete system includes objective lens, microlens array group and two-dimensional array pinhole plate

Embodiment Construction

[0022] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.

[0023] as attached Figure 1As shown, the sample 101 is imaged on the image plane 103 through the objective lens 102, and the image plane is located on the object focal plane of the microlens array group. The microlens array group is composed of two lens arrays 104 and 105 of N×M (N≥2, M≥2) with the same structure, the same optical performance, the same arrangement, and the same arrangement direction, that is, the two microlens arrays contain The number and arrangement of lenses, as well as the dimensions, focal length and transmittance of each lens are the same. The objective lens here can be a microscope objective lens, or a telescopic objective lens or a photographic objective lens, and the microlens array can be a self-focusing lens array, or other types of microlens arrays. A two-dimensional array pinhole plate 106 is placed on t...

Abstract

This invention relates to one two-dimension space simultaneous spectrum resolution method and device, which is made by the following process: forming one two-dimension space lattice by one pair of same lens matrix and one needle matrix board; then calibrating into parallel beam through calibrator; realizing two-dimension space beam by splitting element; imaging on the lattice detector by the dispersed beam through beam focusing lens and relay optical system to form wave spreading two-dimensional scattered spot images responding to one dispersed spectrum by different scattered spots; realizing the one time imaging to get the two-dimensional space intensity image and spectrum distribution images.

Description

technical field [0001] The present invention relates to spectroscopic techniques. It is a novel method and device for realizing two-dimensional simultaneous spectral imaging by using a lens array. Background technique [0002] The spectroscopic instrument is the most basic test equipment in the study of spectroscopy and spectroscopic technical issues. Its purpose is to obtain the information of the material composition and structure through the measurement of the material spectral intensity signal. It is an analytical instrument widely used in the fields of physics, chemistry, biomedicine and environmental science. The dispersion principle of traditional spectroscopic instruments belongs to spatial separation spectroscopy, that is to say, the spectra are regularly arranged in space in the order of wavelength. Therefore, traditional spectroscopic instruments are composed of an incident slit, a spectroscopic system and a detection system. The light beam enters the spectrome...
