LIGHT RECEPTION SENSITIVITY MEASURING METHOD AND AN EVALUATING SYSTEM USING THE SAME CAPABLE OF MEASURING THE RECEPTION SENSITIVITY OF OPTICAL SIGNALS AND DETECTING PROPERTIES OF A TARGET OBJECT BASED ON THE OPTICAL SIGNALS

摘要

PURPOSE: A light reception sensitivity measuring method and an evaluating system using the same are provided to effectively detect not only lights emitted by a target object but also light reception sensitivity.;CONSTITUTION: An evaluating system includes a beam divider (13), a first damping filter (14), a first diffuser (16), and an optical power measurement reference device (18). The beam divider divides optical signals being inputted and sends to first and second paths. The first damping filter damps the optical signals sent to the first path and outputted. The first diffuser distributes optical signals outputted by the first damping filter. The optical power measurement reference device detects the optical signals diffused by the first diffuser and inputted and measures reception sensitivity based on the amount of the optical signals damped by the first damping filter, the cross-sectional area of a detector detecting the optical signals, and a preset correction value.;COPYRIGHT KIPO 2013;[Reference numerals] (11) Light attenuator; (2) Light source
