The circuit principles and singlechip data processing program for the optical power meter are illuminated. A kind of optical element with high sensitivity and reliability is choosen for the circuit design. The element is photodiode-FU15PD which insures the transferring optic reliability in receiving optical fiber. A 16 bits A/D chip CS5529 and a high speed singlechip AT89C51 are used for achieving high measuring accuracy and high computing rate. High performance was been achieved with the above three high performance elements, and this method has been used in practice.
