“…Thus, the application of this technique is narrow in extracting fullfield vibration data. Further discussions of holographic interferometry were presented in many references [9][10][11]. Shearography has been shown to be more resilient to rigid body motion than ESPI or holographic interferometry and may be better suited for industrial applications [12], such as the production and development in the areas of aerospace, wind rotor blades, automation and materials research.…”

“…The system is based on a two-beam interferometry technique which was successfully applied to observe the surface displacement of butterflies' wings. 28,29 These insects also present a similar feather effect due to superficial scales on their wings which modify among other features such as the manner in which the light scatters. 30 In order to have a real response, no special preparation was done on the feathers.…”

Abstract. Optical techniques such as speckle pattern interferometry are well known in the nondestructive testing measurement community. They can be used, for instance, as a predictor of the mechanical behavior of a sample under study. However, in almost all circumstances, a mathematical model has to be applied in order to make sense of these measurements. This is a critical issue when an organic sample is studied, mainly due to its complex deformation response. A good example of this is observed in the birds' feathers. They have extraordinary mechanical and aerodynamic properties thanks to their stiffness and lightness. A couple of live birds are safely situated in front of an out-of-plane sensitive digital holographic interferometer (DHI), an optical system capable of recovering the optical phase in this type of nonrepeatable or unpredictable experiment. In order to recover the backscattering signal and its interferometric response, several images are recorded from different sections of the plumage. Displacement maps are obtained from what is, as far as is known, the first time that full field microdisplacement maps are presented over a hummingbird and a parakeet plumage.

“…Starting from Denis Gabor's principle introduced for holography, many branches have since been developed with different applications: digital in-line holographic microscopy [1]- [3], digital off-axis holographic microscopy [4,5], holographic interferometry [6], holographic memories [7], to name but a few. The main difference between classical holography and new techniques is the recording media.…”

We present our study regarding a compact system design for cell counting and simultaneous 3D imaging, based on digital in-line holographic microscopy configuration. The system is built around the known experimental configuration which includes a pinhole but we also investigate the configuration with a monomode fiber as a light source. Considered samples consist of a very low concentration of cells in flow in a microchannel. The main challenge in our design is to obtain the digital hologram of one cell on a regular video camera sensor in proper resolution conditions, as opposed to the usual configurations where the aim is to visualize a large area. This fact is possible with shorter distances between pinhole and sample and with pinholes with diameters slightly larger than 1micron. These can now be realized by considering the microtechnological processes for microchannel and pinhole fabrication on the same substrate with high refractive indexto increase the numerical aperture of the system The geometrical parameters are established after the numerical analysis of the diffracted field from a single cell and of the entire system numerical aperture values.
