Abstract
The key issues that the LD used in the field of sensing and monitoring as light source is to ensure its safety and stable output power. This paper presents a new method to ensure the stable output power and designs a circuit, including the automatic power control (APC) circuit and automatic temperature control (ATC) circuit. Through its application in the oil contamination sensor, its reliability and validity is proved.
