We present wavelength-multiplexed phase-shifting incoherent multicolor digital holography, which is a technique that records wavelength-multiplexed holograms with general light sources and obtain a 3D multicolor image by applying wavelength-multiplexed phase-shifting interferometry. Compared with the conventional time-division method, there is no need for a mechanically moving component and the number of recorded images can be reduced. Therefore, speeding up of the measurement is expected particularly when using white-light illumination. In this study, we constructed systems using light emitting diodes (LEDs) and obtained reconstructed images of a reflective object and transparent objects, and then quantitatively evaluated them with the images obtained by a conventional method. |
