Light source device and endoscope imaging system

Abstract

The invention provides a light source device and an endoscope imaging system.The light source device comprises a light source assembly used for emitting illumination light, a first rotating part, a second rotating part and a third rotating part, wherein the first rotating part, the second rotating part and the third rotating part are arranged on the light emitting side of the light source assembly and are sequentially arranged in the light emitting direction of the light source assembly; the rotating axes of the first rotating part, the second rotating part and the third rotating part are parallel to the light emitting direction of the light source assembly; the first rotating piece comprises a first empty hole and a disc face which are arranged around the rotating axis of the first rotating piece. The second rotating piece comprises a plurality of narrow-band optical filters which are arranged around the rotating axis of the second rotating piece; the third rotating piece comprises a red light filter, a green light filter, a blue light filter and a third empty hole which are arranged around the rotating axis of the third rotating piece. According to the light source device, through mutual cooperation of the first rotating part, the second rotating part and the third rotating part, various image sensors can be compatible and matched to achieve the hyperspectral shooting imaging function, compatibility is high, and the overall size of the light source device can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a light source device and an endoscope imaging system. Background technique [0002] Endoscopic imaging devices are often used in modern medicine to observe important organs and tissues inside the human body. Doctors can make a preliminary diagnosis of diseases through the color image information of mucous membranes or tissues and organs inside the human body. [0003] Hyperspectral imaging technology is a combination of spectral technology and imaging technology, that is, after using multiple narrow-band lights to irradiate the object, it can image the objects in each spectral band. Different tissues in the human body have specific absorption spectra. By using hyperspectral imaging technology and narrow-band spectral identification, the structure and information of different biological tissues of the human body can be distinguished, and different lesions of different...
