Wavelength scanning digital holography (DH) can measure the shape of an object from the correlation between wavelength and phase, but the long measurement time associated with wavelength scanning has been a problem. In this study, we conducted a basic study on high-speed wavelength scanning DH using an optical frequency comb.
