specific example
[0033] Take a specific example as an example: figure 1 , is the data flow diagram from the mirror body to the endoscope host processing unit / cold light source. The optical system in the mirror body is imaged and converted into digital electrical signals by CMOS processing and sent to the first electro-optic conversion unit, and then converted by the first electro-optic conversion unit Be the light image signal of wavelength I (such as being 1530nm); The mirror information stored in the non-volatile data storage device in the mirror such as ferroelectric etc., can be ID information, model information etc., be converted into wavelength by the first electro-optical conversion unit II (for example, 1550nm) optical mirror body signal I; various sensors in the mirror body, such as the sensor signals generated by the temperature sensor at the head end of the mirror body, the photosensitive sensor, etc., are converted into wavelength III (for example, 1570nm) by the first electro-optic...

The invention provides an optical communication structure and an electronic endoscope system. The optical communication structure comprises an electro-optical conversion unit connected with the outputend of the signal transmitting main body. The electro-optical conversion unit converts different electric signals emitted by the main body into optical signals with different wavelengths. The outputend of the electro-optical conversion unit is connected with the input end of the amplitude-phase modulation module; the output end of the amplitude phase modulation module is connected with the inputend of the optical combiner. The output end of the optical combiner is connected with the first end of the optical fiber. The second end of the optical fiber is connected with the optical splitter. The output end of the optical splitter is connected with the input end of the coherent optical detection demodulator. The output end of the coherent optical detection demodulator is connected with theinput end of the photoelectric conversion unit, and the photoelectric conversion unit is connected with the signal receiving body and converts optical signals of different wavelengths into electric signals and sends the electric signals to the signal receiving body. The optical communication structure can directly perform various signal compensation processes by adopting a coherent optical technology.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to an optical communication structure and an electronic endoscope system. Background technique [0002] At present, in the field of medical endoscopes, the scene in the cavity is captured by the endoscope body equipped with a camera, and is displayed on a display after being processed by a processing device. The image captured by the camera is generally transmitted to the processing device via metal wires. In order to solve the problem of electromagnetic interference, improve the channel bandwidth and realize the overall waterproof of the mirror body, it is proposed to use light instead of electricity to transmit the image signal, but the image signal of the prior art and The control signal of the mirror body is divided into different channels for transmission, for example, the image signal is transmitted by the first light, and the control signal is transmitted by electricity / secon...
