WebAn optical detector is a transducer that converts an optical signal into an electrical signal. It does this by generating an electrical current proportional to the intensity of incident optical radiation. The relationship between the input optical radiation and the output electrical current is given by the detector responsivity. http://www.chem.ucla.edu/~craigim/pdfmanuals/appnotes/an1003 philips s3601
