With the reform of the national medical system, the progress of medical technology, and the popularization of advanced medical equipment, the endoscope equipment system is increasingly widely used in hospitals at all levels, such as: ventriculoscope, thoracoscope, otorhinolaryngoscope, hysteroscope, ureterorenoscope, prostate electrotomy mirror, intervertebral disc mirror, arthroscope, laparoscope, etc. What is the imaging principle of medical endoscope camera system?
Imaging principle of the medical endoscope imaging system: the light from the light source is transmitted to the human body through the main body of the endoscope through the transmission beam (optical fiber) to illuminate the part of the human body cavity that needs to be inspected. The objective lens images the part to be inspected on the area array CCD. The CCD drive circuit controls the CCD to collect images and output standard video signals. The adjusting mechanism is used to adjust the viewing angle of the front end of the endoscope, which can be adjusted up and down, left and right, and rotated.
The medical endoscope camera system includes five parts: optical mirror, medical camera, medical monitor, cold light source and recording system;
Among them, the medical camera adopts single crystal and tri crystal, and now the high-end customers are mostly 3CCD cameras. The medical tri chip image sensor can reproduce realistic colors, output 1920 * 1080P, 60FPS full HD digital signals, provide a stable endoscopic field of vision, give the operator an excellent visual experience, and make the operation easier and more refined!
The development of cold light source includes halogen lamp xenon lamp LED lamp;
Features and benefits of LED cold light source
1. LED uses cold luminescence technology, and its heat output is much lower than that of ordinary lighting fixtures.
2. Pure white light, free of infrared and ultraviolet rays;
3. Incredibly long usage time (60000 to 100000 hours)
4. Pleasant low-cost experience (no need to change the bulb)
5. Ultra low energy consumption, green and environmental protection
6. Touch screen
7. Security
