We propose and experimentally demonstrate a system in which off-axis digital holographic microscopy is realized using a broadband illumination source. Single-shot holographic measurements are enabled, while the coherence noise is removed thanks to th

A portable camera system based on holographic elements is demonstrated which can be attached to the camera port of a conventional microscope for complex wavefront analysis. The full-field off-axis holograms provide the whole sample information.

We have recently introduced a method based on a volume diffractive element (VDOE) to correct the coherence plane tilt in off-axis DHM. The VDOE consists of two phase gratings recorded on a photopolymer (BAYFOL® HX) from Bayer MaterialScience AG, eac

A Volume Diffractive Optical Element (VDOE) is placed in the reference arm of an off-axis short coherence DHM enabling nanometric-resolution surface topography in short coherence and high-speed vertical scanning, through field of view enlargement.

In digital holographic microscopy (DHM), the long coherence length of laser light causes parasitic interferences due to multiple reflections in and by optical components in the optical path of the microscope and thus degrades the image quality. The p
