Endoscopic detection device for lateral spectrum detection

Abstract

The invention aims to overcome the defects in the prior art. The invention provides an endoscopic detection device for lateral spectrum detection. Laser with good coherence and wide spectral propertyis generated by using super-continuum spectrum laser; after a cylindrical lens is used, the light is focused on a linear port of an optical fiber bundle; the N paths of light are transmitted to a detection port by the optical fiber bundle; high-efficiency broadband illumination is realized; N inclined surface end surface optical fibers are arranged at a probe port; the super-continuum spectrum laser is laterally emitted; according to the method, a side object is illuminated, backscattered light of the side object is received at the same time, the backscattered light is transmitted through an optical fiber and then synchronously detected through a multi-channel spectrum detection module, the time error of a system is reduced, a spectrum difference algorithm and a convolution algorithm are further used for processing spectrum data, and the relative content ratio of biomolecules is extracted.

Description

technical field [0001] The patent of the invention belongs to the field of optical detection, and specifically relates to an endoscopic detection device for lateral spectrum detection. Background technique [0002] The endoscopic probe is a photoelectric detection instrument that integrates photoelectric engineering, electronic technology, and precision instruments. It has a very wide range of applications in the field of biomedical engineering. For example, the endoscopic probe technology can enter the human body through oral cavity and other channels to help The doctor detects the symptoms of the patient's stomach, and the endoscopic probe can observe the diseases that cannot be observed by X-rays. The doctor can formulate a scientific treatment plan based on this. At the same time, the current spectral detection technology has ushered in rapid development. The feature of "different spectra for different objects" can obtain the spectral information of the object of interes...

AI Technical Summary

Problems solved by technology

[0003] However, spectral detection instruments are usually large in size and need to be combined with endoscopic optical fibers to obtain spectra in tiny spaces

However, the traditional optical fiber probe can only detect the spectrum in a small range, and cannot provide more comprehensive spectral data

Moreover, traditional fiber optic probes usually detect spectral data in the forward space, while ignoring the spectral detection in the lateral space
