In this paper, dual-wavelength digital holography is demonstrated by both numerical
simulation and experiment. Simulations were done for two wavelengths of 500 nm and 550 …

In this work multiwavelength digital holography, originally applied to calculate the volume
displacement of various macroscopic topographic surface features, is now extended to the …

We report the development of a simple commercial digital holographic microscope. The
hologram is recorded using a CCD sensor and numerically reconstructed to provide …

More than 40 years ago, D. Gabor/1/proposed a new principle of microscopy to overcome
the limitations of lenses. Using a coherent ensemble of particles with wave nature, the …

Digital holography uses phase imaging in a variety of techniques to produce a three-
dimensional phase resolved image that includes accurate depth information about the …

Digital holography requires precise phase analysis without wavefront aberration from
defocusing errors. While the auto-contrast method is generally advantageous for refocusing …

We simultaneously capture holograms using multiple wavelengths with a single camera
using off-axis holography. Our prototype uses two tunable lasers and the references or local …

Digital holography enables high-precision quality control in machining production and has
already been introduced to several multi-axis systems1, 2. To meet the demanding …

We demonstrate lensless single-shot dual-wavelength digital holography for high-speed 3D
imaging in industrial inspection. Single-shot measurement is realized by combining off-axis …

In this work, multi-incident digital holographic profilometry for microscale measurements is
presented. This technique assembles the set of object fields from captured holograms for …
