Micro-multispectral fluorescence reception and treatment system

Abstract

The invention discloses a micro-multispectral fluorescence reception and treatment system. The micro-multispectral fluorescence reception and treatment system comprises an excitation unit, a fluorescence collection unit and a data processing unit, wherein the excitation unit comprises an excitation light source, an exciting light filter and an optical convergence component; the fluorescence collection unit comprises a photoelectric converter and a micro-optical filter which is attached to the photoelectric converter closely; and the micro-optical filter is a highly integrated multi-channel optical filter. An object to be imaged radiates the fluorescence with a specific wavelength under the excitation of irradiation light of the excitation unit; the optical convergence component converges the fluorescence; then the converged fluorescence is irradiated to the photoelectric converter through the micro-optical filter; the photoelectric converter acquires corresponding image information according to a fluorescence signal; and the data processing unit analyzes and processes the image information and outputs a result. The system can collect multiple fluorescence signals of stimulated radiation and acquire image information in a high-efficiency and low-cost way, and can accurately and objectively reflect detection results in real time.

Description

Technical field [0001] The invention relates to biochemical detection and in vitro medical diagnosis equipment, in particular to a micro-multispectral fluorescence receiving and processing system. Background technique [0002] At present, the instruments used in clinical diagnosis and biological testing in medical institutions and the fluorescence collection systems adopted are all characterized by polymerase chain reaction (Picymerase Chain Reaction) PCR. A primer containing a fluorescent substance is added to the PCR reaction system. The fluorescent substance emits light of another characteristic wavelength under the irradiation of an excitation light source of a specific wavelength. The PCR reaction is detected by the photomultiplier tube, optical fiber optical signal transmission, and discrete filter spectroscopy. During the process, the intensity of light emitted by the fluorescent substance can be used to monitor the progress of the PCR amplification reaction. Through comp...
