Abstract
The invention relates to a gastroscope imaging system with multi-angle irradiation, and belongs to an irradiation imaging device of a gastroscope probe part. The gastroscope imaging system is sequentially provided with a first lens, a dot light source array, a second lens and an image sensor from the end part. The dot light source array is arranged on a rear focus plane of the first lens and comprises a frame and dot light sources arranged on the frame. A transmitting window is arranged on a frame part between the two adjacent dot light sources. The image sensor is arranged at the rear focus of the second lens. The target placed at the focus of the first lens forms parallel light through the first lens, passes through the transmitting window on the dot light source array and is converged through the second lens and imaged by the image sensor. The system provided by the invention can irradiate with parallel light with determined angles from many directions to facilitating finding disease positions and degrees.
Description
Technical field
A kind of gastroscope imaging system with multi-angle illumination belongs to the illumination imaging device of gastroscope probe segment.
Background technology
Gastroscope is a kind of medical inspection method, also refers to the utensil that this inspection is used.It stretches in the stomach by very thin, a soft pipe, and the doctor can the direct observation esophagus, the duodenal pathological changes of harmonization of the stomach, especially to small pathological changes.
Present stage, more be to utilize about one a centimeter black plastic of diameter to wrap up fiber-optic elongated pipe, front end is equipped with endoscope by the esophagus → stomach that stretches into the person under inspection in the mouth → duodenum, the high light that is sent by the light source device, via optical fibers light is turned, allow the doctor clearly observe the health status at each position in the upper digestive tract from the other end.
This method adopts the floodlighting mode in order to make positions such as stomach, duodenum by blur-free imaging.This mode can illuminate whole internal organs, and the convex-concave structure that makes pathological changes bring is not easy not find, even find also to be not easy to judge the pathological changes degree of depth by picture, therefore also just gives and judges that lesion degree brings difficulty.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of gastroscope imaging system with multi-angle illumination, not only can throw light on to lesion locations with the angle of incidence of determining as required, and can realize multi-angle illumination, more be conducive to find lesion locations and lesion degree, do not influence same imaging shaft simultaneously.
The object of the present invention is achieved like this:
A kind of gastroscope imaging system with multi-angle illumination from the end, sets gradually first lens, pointolite array, second lens and imageing sensor; Described pointolite array places the back focal plane of first lens, comprises framework and the point source that is arranged on the framework, and the frame part in the middle of adjacent two point sources is provided with light inlet window; Described imageing sensor places the back focus position of second lens; Place the target at the first lens focus place to become directional light through first lens, the light inlet window on the crossing point array of source is assembled through second lens, by the imageing sensor imaging again.
Above-mentioned a kind of gastroscope imaging system with multi-angle illumination, described point source are to utilize the superminiature LED of MEMS technology processing.
Above-mentioned a kind of gastroscope imaging system with multi-angle illumination, described light inlet window is the entity that through hole or transparent material are made.
Because the present invention has the gastroscope imaging system of multi-angle illumination, because pointolite array places the back focal plane of first lens, therefore realize parallel light emergence, form the illumination that certain determines angle, because point source becomes array format to arrange, therefore can realize the illumination of multi-angle, avoid existing all angles of lighting system to throw light on simultaneously and cover the problem of some important pathological changes information; Because pointolite array is provided with light inlet window, therefore can realize the same imaging shaft of diseased region.
Description of drawings
Fig. 1 is the gastroscope imaging system that the present invention has multi-angle illumination.
Fig. 2 is the structural representation of pointolite array.
Among the figure: 1 first lens, 2 pointolite arrays, 21 frameworks, 22 point sources, 23 light inlet windows, 3 second lens, 4 imageing sensors.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is described in further detail.
Specific embodiment one
The gastroscope imaging system structural representation with multi-angle illumination of present embodiment as shown in Figure 1.This gastroscope imaging system sets gradually first lens 1, pointolite array 2, second lens 3 and imageing sensor 4 from the end;

Described imageing sensor places the back focus position of second lens 3; Place the target at first lens, 1 focus place to become directional light through first lens 1, the light inlet window 23 on the crossing point array of source 2 is assembled through second lens 3, by imageing sensor 4 imagings again.
Double-head arrow among Fig. 1 represents that from the illuminating ray of pointolite array 2 outgoing single arrow is represented the imaging light from target reflection.
Above-mentioned gastroscope imaging system with multi-angle illumination, described point source 22 adopts superminiature LED for utilizing the superminiature LED of MEMS technology processing, is more suitable for the luminaire miniaturization, making does not need to increase the diameter of gastroscope probe, just can gatehead array of source 2.
Above-mentioned gastroscope imaging system with multi-angle illumination, described light inlet window 23 is through hole, can increase translucent effect like this.
Specific embodiment two
The gastroscope imaging system with multi-angle illumination of present embodiment with the different entities that are that described light inlet window 23 is made for transparent material of specific embodiment one, can increase the intensity of pointolite array 2 like this.
Specific embodiment three
The different entities that are that described light inlet window 23 and framework 21 are made for same transparent material of present embodiment and preceding two embodiment.
