Electro-optical polarization spectrometry microscope

Abstract

The invention discloses an electric light type polarization spectrum measuring microscope which is based on an ordinary optical microscope structure and is added with a fixed linear polarizer, a fixed electric light polarization apparatus and a series of optical apparatus that are combined with each other. Incidence light passes through the fixed linear polarizer firstly; the penetrating vibration angle of the fixed linear polarizer is invariable at the same time; then the linear polarized light passes through the fixed electric light polarization apparatus; an electric field or a magnetic field with an expected strength is applied to the fixed electric light polarization apparatus to ensure that the polarization angle of linear polarized light is changed correspondingly; emergent ray polarized light passes through a sample to be observed on an object stage; the polarized light penetrates the sample or is reflected on the surface of the sample and then passes through a polarization analyzer; light intensity information is collected by a charge coupled device (CCD); and the polarization information is stored and displayed finally. Different samples have different effects on the polarized light, so that the linear polarized light passing through the sample to be observed can show different polarization optical characteristic. Relative polarized spectral line is picked up by information processing technology, and various optical characteristics of the sample to be observed can be analyzed.

technical field [0001] The invention relates to a polarization optical microscope, in particular to an electro-optic polarization spectrum measuring microscope. Background technique [0002] The sample is placed in an electro-optic polarization spectrum measurement microscope system for polarization spectrum measurement. The obtained polarization spectrum can characterize the microscopic specificity of the sample, which plays an important role in the research, analysis and identification of the microscopic state of the sample and related optical properties. role. Therefore, the polarization optical microscope used to measure the polarization spectrum of samples has important application value for improving the research level of biotechnology and medical clinical detection. However, the current polarizing microscope detects linear polarization information by manually rotating the device to observe light intensity signals in different polarization states.

Problems solved by technology

This structure cannot capture full polarization information that can accurately characterize physiological properties

However, relying on mechanical rotation to change the polarization angle, continuously recording data and real-time processing to obtain full polarization information requires high data accuracy. error in judgment

Although other high-end microscopes can directly realize the functions of this patent and have higher precision, the equipment of these microscopes is of high value, complex in structure, cumbersome to operate, and requires a lot of expenses for maintenance. Many researchers cannot conveniently use these microscopes for various reasons. The equipment observes the microstructure in the sample, so it cannot be widely used for the time being
