A Microscopic Imaging System for Obtaining Appearance Image and Element Distribution Image Simultaneously

Abstract

The invention discloses a microscopic imaging system for obtaining appearance images and element distribution images at the same time, which mainly includes: a laser, which emits short-pulse laser signals; an illumination source, which emits visible light signals; reflector, so that the optical signals sent by the laser and the illumination light source are transmitted vertically downward; the objective lens is located below the refraction and reflection optical path, and the optical signal transmitted vertically downward passes through the objective lens and is irradiated on the On the object to be detected under the objective lens; a moving mechanism, which moves the optical signal or the object to be detected, so that the optical signal traverses all parts of the object to be detected. The invention organically combines LIBS analysis technology and laser scanning confocal technology, uses spectral microscopic imaging technology to realize point-by-point scanning of the sample to be tested, and realizes a microscopic imaging system that simultaneously obtains appearance images and element distribution images.

Description

technical field [0001] The invention relates to a microscopic optical imaging technology, in particular to a microscopic imaging system for simultaneously obtaining appearance images and element distribution images. Background technique [0002] High-resolution micro-optical imaging technology is a way for people to shift from the macro to the micro, to reveal the composition and regulation mechanism of life in real time at the cellular molecular level, to obtain a series of original scientific discoveries, and to realize the comprehensive cross-integration of life science, physics, chemistry and other disciplines. important means. From the earliest conventional microscopes to the current super microscopes, such as super-resolution microscopes, two-photon microscopes, and tunneling scanning microscopes, it can be said that the emergence of each new imaging technology is a milestone. With the emergence of laser technology, the application of the interaction between light and...

Problems solved by technology

However, the traditional LIBS needs to use a relatively complex spectral analysis system, which requires a large amount of test data and a long processing time; moreover, once the sensitivity of the spectral analysis system is insufficient, it is necessary to increase the intensity of the plasma signal by increasing the intensity of the excitation light. While measuring the damage of the object, the spatial resolution is greatly reduced

Therefore, in terms of microscopic imaging, the application of LIBS has great limitations.
