发明名称 LIGHT SOURCE CONTROL SYSTEM
摘要 A system and method for controlling an optical light source is provided. A current source drives the light source, while the voltage across and the current through the light source is measured. The voltage and current are converted to digital signals and se nt to a neural network, which generates a modeled optical output power of the light source and a modeled value of the optical wavelength. A control circuit receives the modeled optical output power and wavelength and sends a control signal to the current source to minimize the difference between the desired power output and the modeled output power. In addition, a control signal is sent to a Pettier driver to control the temperature of a Pettier cooler i n order to increase or decrease the wavelength emitted by a laser diode.
