Polarization imaging of a 3D object by use of on-axis phase-shifting digital holography

Abstract

A polarimetric imaging method of a 3D object by use of on-axis phase-shifting digital holography is presented. The polarimetric image results from a combination of two kinds of holographic imaging using orthogonal polarized reference waves. Experimental demonstration of a 3D polarimetric imaging is presented.

Progress in development of imaging polarimeter for Stokes parameter measurement

“…Polarization information is correlated with features of the interface such as index of refraction, shape, roughness, most of which are uncorrelated with spectral and intensity images. Thus imaging polarimeter has the potential to be used in target detection and identification in clutter [1,2] , stereoscopic imaging [3] and so on. Polarimeters have also been used in atmospheric sensing applications, including aerosol properties analyze [4] , particulates (water/ice phase) in clouds discrimination.…”

Phase and Polarization Contrast Methods by Use of Digital Holographic Microscopy: Applications to Different Types of Biological Samples

“…The advantages of DH over the other polarimetries are its relatively simple optical system without any rotating optics and its adaptability to three dimensional objects due to numerical focusing (Nomura et al, 2007). Polarization microscopy can reveal inner structures of cells without the need of contrast agents, and it is possible to give access to intrinsic information about their morphology and dynamics through the phase change quantification in these microscopic structures.…”

Construction of a portable parallel phase-shifting digital holography system

“…The technique is capable of an instantaneous 3D measurement and is researched in many fields: microscopy, 4, 5 shape measurement, 6, 7 particle measurement, 8,9 object recognition, 10, 11 polarization analysis, 12,13 and so on. However, it is impossible for image sensors to record fine interference fringes.…”
