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 part.
Background technology
Gastroscope is a kind of medical inspection method, also refers to this utensil checking use.It stretches in stomach by very thin, a soft pipe, and doctor directly can observe esophagus, the duodenal pathological changes of harmonization of the stomach, especially to small pathological changes.
Present stage, more utilize the black plastic of a diameter about a centimeter to wrap up fiber-optic elongate tube, endoscope is equipped with by the esophagus → stomach → duodenum stretching into person under inspection in mouth in front end, by the high light that light source device sent, light can be made to turn via optical fibers, allow doctor clearly observe the health status at each position in upper digestive tract from the other end.
This method, in order to make the positions such as Stomach duodenum by blur-free imaging, adopts floodlighting mode.This mode can illuminate whole internal organs, and the convex-concave structure that pathological changes is brought is not easy not find, even if find also to be not easy to judge injured depth by picture, is therefore also just judged that lesion degree brings difficulty.
Summary of the invention
In order to solve the problem, the present invention devises a kind of gastroscope imaging system with multi-angle illumination, not only can throw light on to lesion locations with the angle of incidence determined as required, and can multi-angle illumination be realized, more be conducive to finding lesion locations and lesion degree, do not affect same imaging shaft simultaneously.
The object of the present invention is achieved like this:
There is a gastroscope imaging system for multi-angle illumination, from end, set gradually the first lens, pointolite array, the second lens and imageing sensor; Described pointolite array is placed in the back focal plane of the first lens, comprises framework and is arranged on the point source on framework, and the frame part in the middle of adjacent two point sources is provided with light inlet window; Described imageing sensor is placed in the back focus position of the second lens; The target being placed in the first lens focus place becomes directional light through the first lens, the light inlet window on crossing point array of source, then assembles, by imageing sensor imaging through the second lens.
Above-mentioned a kind of gastroscope imaging system with multi-angle illumination, described point source is the superminiature LED utilizing MEMS technology to process.
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 is placed in the back focal plane of the first lens, therefore parallel light emergence is realized, form the illumination that certain determines angle, because point source becomes array format to arrange, therefore can realize the illumination of multi-angle, avoid all angles of existing lighting system throw light on simultaneously and cover the problem of some important Pathological Informations; Because pointolite array is provided with light inlet window, the same imaging shaft of diseased region therefore can be realized.
Accompanying drawing explanation
Fig. 1 is the gastroscope imaging system that the present invention has multi-angle illumination.
Fig. 2 is the structural representation of pointolite array.
In figure: 1 first lens, 2 pointolite arrays, 21 frameworks, 22 point sources, 23 light inlet windows, 3 second lens, 4 imageing sensors.
Detailed description of the invention
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 the present embodiment as shown in Figure 1.This gastroscope imaging system, from end, sets gradually the first lens 1, pointolite array 2, second lens 3 and imageing sensor 4;
Described pointolite array 2 is placed in the back focal plane of the first lens 1, the point source 22 comprising framework 21 and be arranged on framework 21, and framework 21 part in the middle of adjacent two point sources 22 is provided with light inlet window 23, and the structural representation of pointolite array 2 as shown in Figure 2; The hot spot that this design can make any one point source 22 on pointolite array 2 launch, all penetrates from the first lens 1 with the form of directional light, realizes throwing light on to certain angle parallel of lesion locations;
Described imageing sensor is placed in the back focus position of the second lens 3; The target being placed in the first lens 1 focus place becomes directional light through the first lens 1, the light inlet window 23 on crossing point array of source 2, then assembles through the second lens 3, by imageing sensor 4 imaging.
Double-head arrow in Fig. 1 represents the illuminating ray from pointolite array 2 outgoing, and single arrow represents the imaging light from target reflection.
The above-mentioned gastroscope imaging system with multi-angle illumination, the described superminiature LED of point source 22 for utilizing MEMS technology to process, adopts superminiature LED, is more suitable for luminaire miniaturization, make the diameter not needing to increase gastroscope probe, just can gatehead array of source 2.
The 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 the present embodiment, is from the different of specific embodiment one entity that described light inlet window 23 is made for transparent material, can increases the intensity of pointolite array 2 like this.
Specific embodiment three
From the different of the first two embodiment, the present embodiment is that described light inlet window 23 and framework 21 are the entity that same transparent material is made.
