Abstract

In this paper, phase quantitative measurements using digital holography (DH) with low-coherence light sources are presented. Compared with conventional laser-based DH, low-coherence light sources have advantages of better image quality, less speckle noise, and smaller system configurations. As a light source, we utilized light-emitting diode (LED) and quantum dot (QD) film. In particular, quantum dot film emits low-coherence lights with adjustable wavelength and high conversion efficiency, which has versatility for additional methods including dual-wavelength reconstruction. Experimental results verify the quality enhanced quantitative measurement of proposed methods compared with conventional systems.
