Control system for precise power laser measurement

This paper describes steps involved in a designing of a control system for precise power laser measurement. Main goal of this research consists in developing precise laser driver and measurement system for power laser measurement. This control system can be used in various type of measuring applications for instance measuring of distance, pressure and temperature. Control system allows precise driving of two different laser diodes independently on each other with measuring of emitting optical power and includes photodiode for power optical sensing.
