Abstract
An image sensor for the two-dimensional (2-D) synchronous detection of temporal properties of modulated optical wave fields is presented. Each pixel of this multitap lock-in CCD is capable of acquiring all optical data for the extraction of modulation amplitude, relative phase, background level, and higher order Fourier coefficients. By employing the pixels´ offset subtraction stages, a dynamic range of >100 dB was obtained experimentally
