Paper Title:
Design and Linear Fitting of High Sensitive Optical Power Meter
  Abstract

This paper introduces the hardware design of digital optical power meters and the algorithm flow.The power meter detector, with InGaAs-PIN photodiode and LTC6078,is used as a preamplifier for the measurement of micro-current;Silicon Laps C8051f410 are selected as the micro-controller for AD quantification and data processing, and the linear fitting of the measured data and standard data is completed in Matlab environment.After the comparison between the two measurement results,the proposed optical power meter adopts certain algorithm to compensate the deviation and improve the overall performance.The analyses of measured data show that:the optical power meter can be designed to precisely measure multi-wavelength with wide dynamic range and high sensitivity,support AC and DC dual power supply,and be portable.Therefore It also can be used both by university laboratories for teaching and by government department for construction monitoring and optical communications maintenance.
