Paper Abstract

We demonstrate the confocal phase imaging at a video rate by a combination of dual comb spectroscopy (DSC) with 2D spectral encoding (2D-SE). After the image pixels of the sample is encoded on an optical frequency comb (OFC) by 2DSE, DSC of the image-encoded OFC passing through the confocal pinhole gives the mode-resolved amplitude and phase spectra. Based on one-to-one correspondence between the image pixels and OFC modes, the confocal amplitude and phase images are decoded from the mode-resolved amplitude and phase spectra, respectively. The phase spectrum measurement without the need for mechanical scanning enables the video-rate confocal phase imaging.
