Endoscopy combined with advanced technology

1. Electronic endoscope uses advanced microelectronic devices to replace the fiber guide beam and eyepiece of the soft optical guide fiber of the traditional endoscope. Through the charge synthesis device CCD installed at the tip of the endoscope, the transmitted optical image is converted into an electronic image, which is transmitted to the image processor through the cable, and the image is reproduced on the display after video processing.

An electronic endoscope can be used to view images directly using an LED display, which is actually a combination of optical, mechanical,

A medical device integrated with electronic computer technology [3]. The CCD solid-state camera at the tip, which converts optical images A/D and is then exported by wires for display on an LED display, is equivalent to a television camera being fed into a body cavity, in effect a miniature color photography system.

Second, the CCD video endoscope used at present can be connected with the camera, video camera or computer, to form a photographic, photographic and image processing system, so as to detect, record, store and image analysis of the field of view target, to provide a good guarantee for diagnosis and processing.

The so-called CCD Chinese full name is: charge coupling element. Can be called CCD image sensor, also called image controller. The CCD is a semiconductor device that converts optical images into electrical signals. The more images a CCD contains, the higher the resolution it provides.

Three, CCD image sensor function characteristics:

1. Small volume and light weight;

2, power consumption, low working voltage, shock and vibration resistance, stable performance, long life;

3, fast response speed, with self-scanning function, small image distortion, no residual image;

4. High pixel integration and accurate size;

The technical level of Shanghai Yanshun endoscope in industrial testing has reached a higher stage, all aspects can be said to have reached the leading level of the domestic, and is developing to NDT power.
