We demonstrated confocal phase imaging with scan-less dual comb microscopy, in which the confocal 2D image of a sample was encoded on OFC spectrum by the 2D spectral disperser, and then the image-encoded OFC spectrum is acquired by dual comb spectrometer to decode the 2D image. This approach enables us to not only establish both confocality and full-field imaging under the scan-less condition but also depth-resolve the confocal volume of the sample within the wavelength by use of the phase spectrum. We demonstrated a proof-of-principle experiment of the proposed method by confocal phase imaging of a test chart.
