Title:
LASER LIGHT SOURCE BASED ON APPLICATION OF OCT SPECTRAL ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2019/218827
Kind Code:
A1
Abstract:
The present invention relates to a laser light source based on the application of OCT spectral analysis. The laser light source comprises: a laser module; a temperature control circuit, connected to the laser module and used for detecting and regulating a temperature value of the laser module in real time; an MCU module, connected to the temperature control circuit and used for controlling, according to the detected temperature value, the temperature control circuit to regulate the temperature value of the laser module, so that the temperature of the laser module keeps constant; a current control circuit, connected to the laser module and used for collecting and regulating a current value of the laser module in real time. The MCU module is connected to the current control circuit and is also used for controlling, according to the collected current value, the current control circuit to regulate the amplitude of a current output to the laser module, so that the current output to the laser module keeps constant. The constant-temperature and constant-current control of a laser module are realized by providing a temperature control circuit and a current control circuit, so that the performance of the laser light source is stable and reliable.
