In recent years, multilayer photonic bandgap structures comprising stacks of alternating layers of positive and negative index have been proposed for a variety of applications, such as perfect imaging, filters, sensors, coatings for tailored emittanc

In this work, we investigate, both theoretically and experimentally, single-wavelength and multiwavelength digital holographic microscopy (DHM) using telecentric and nontelecentric configurations in transmission and reflection modes. A single-wavelen

Because the objective of holography is to perform phase retrieval from a recorded hologram, this chapter discusses how this can be achieved using analog holographic techniques. Conventional analog holography entails physical re-illumination of the ho

Another application of HI is the generation of a fringe pattern corresponding to contours of constant elevation with respect to a reference plane (see Fig. 7.1). Such contour fringes can be used to determine the shape of a 3D object. Holographic cont

Whereas conventional analog holography (AH) entails physical re-illumination of the hologram of the object with a reading beam and finding the 3D real or virtual image, digital holography (DH) is a numerical procedure that simulates Fresnel diffracti

The book has thus discussed both Gabor and Leith–Upatneiks digital holography with applications in digital holographic interferometry. While it is true that holography yields the 3D shape of the object, it is only possible to deduce this informatio

Digital holography optically generates a hologram, which is then recorded on a CCD camera, and an image is reconstructed using digital techniques. This chapter discusses the converse, i.e., the hologram is digitally generated and the reconstruction i

Different types of interferometers can be used to produce a fringe pattern phase modulated by the physical quantity being measured. Several physical quantities can be measured with interferometric fringe techniques, such as strain and stress analysis
