Measuring the photodetector frequency response for ultrasonic applications by a heterodyne system with difference- frequency servo control
A technique for the calibration of photodiodes in ultrasonic measurement systems using standard and cost-effective optical and electronic components is presented. A heterodyne system was realized using two commercially available distributed feedback lasers, and the required frequency stability and r...
