We report experimental results of parallel measurement of spectral components of the light. The temporal fluctuations of an optical field mixed with a separate reference are recorded with a high throughput complementary metal oxide semi-conductor camera (1 Megapixel at 2 kHz framerate). A numerical Fourier transform of the time-domain recording enables wide-field coherent spectral imaging. Qualitative comparisons with frequency-domain wide-field laser Doppler imaging are provided.
