Parallel multispectral ghost imaging data acquisition with supercontinuum

A wavelength multiplexing with spectral supercontinuum source in computational ghost imaging is implemented and investigated. In our proof-of-concept experiment, we used two diffraction gratings and one spatial light modulator to form up to 10 independent spectral channels. Registration of data by a spectrometer in such a scheme makes it possible to reduce the time of data acquisition by a factor of ten. It was established that an increase the number of spectral channels from 1 to 10 leads to the increase of the contrast-to-noise ratio by the factor of 2.8. This makes the proposed technique attractive for high-speed demanding applications such as communications and remote sensing. •Multiple-wavelength multiplexing computational ghost imaging with spectral supercontinuum is demonstrated.•Practical aspects of the implementation of the experimental scheme are provided.•The quantity of channels proportional accelerates data acquisition.•Optimization of the formed random binary pattern sizes to improve the quality of object image reconstruction is performed.
