Microscopic spectrum imaging system based on mobile phone

Abstract

The invention discloses a microspectral imaging system based on a mobile phone, comprising: a mobile phone imaging device, a lens device, a spectroscopic device, a spectrometer device and a light source; the spectroscopic device includes: a half-transparent mirror and a dichroic mirror; wherein : The light beam emitted by the light source is reflected on the sample to be tested through the dichroic mirror; the sample to be tested reflects the received light beam, and the reflected light is transmitted to the half mirror through the dichroic mirror; The transmitted light of the chromatic mirror, and reflect a part of the transmitted light to the spectrometer device, so that the spectrometer device generates the spectral curve of the sample to be tested according to the received light, and the half-transparent mirror transmits another part of the transmitted light to the lens device; The imaging device receives the light passing through the lens device and generates a magnified image of the sample to be tested. The system has a simple and compact structure, and integrates an optical microscope, a mobile phone, and a spectrometer, enabling rapid acquisition of images and spectra, and improving data acquisition efficiency.

Description

technical field [0001] The invention relates to the technical field of microspectral imaging, in particular to a microspectral imaging system based on a mobile phone. Background technique [0002] Optical Microscope (OM) is an optical instrument that uses optical principles to magnify and image tiny objects that cannot be resolved by the human eye, so that people can extract microstructure information. A spectrometer is composed of a prism or a diffraction grating. It is a scientific instrument that decomposes complex light into spectral lines. The spectrometer can be used to measure the light reflected by the surface of an object. Microspectral analysis is a method that uses an optical microscope as an auxiliary device to collect optical signals in the microscopic area of ​​an object for sample spectral analysis. The traditional microspectral analysis instrument is to load the spectrometer on the basis of the optical microscope, so that the two are integrated in the instru...

Problems solved by technology

[0003] However, the traditional microspectral analysis instruments can only obtain the spectral data of the sample, but not the image data, and the traditional instruments are large in size and high in cost, so they have not been widely used
