Abstract

Boxcar integrator and lock-in amplifier for the detecting of optical small signals are developed based on the virtual instrument technology of LabView. The algorithm of boxcar integrator is simple and easy-achieved. Lock-in amplifier is a powerful technique for the extracting and amplification of small signals. However, the cost of lock-in amplifier hardware is high. We develop digital boxcar integrator and lock-in amplifier in LabView platform. The performances of these two virtual measurement systems for optical small signal are exhibited and analyzed.
