Rapid and economical data acquisition in ultrafast frequency-resolved spectroscopy using choppers and a microcontroller.

Abstract

Spectrometers and cameras are used in ultrafast spectroscopy to achieve high resolution in both time and frequency domains. Frequency-resolved signals from the camera pixels cannot be processed by common lock-in amplifiers, which have only a limited number of input channels. Here we demonstrate a rapid and economical method that achieves the function of a… (More)
