“…3, showing a FINCH system with an extra glass lens L c . 21,24 An object point, positioned at a working distance from the objective lens L o , emits a spherical beam which is introduced into the system. An input polarizer, P 1 , oriented at an angle of 45 deg to the SLM active axis, allows the operation of two different imaging systems in the same physical single-channel setup.…”

“…Finally, reducing the optical path difference (OPD) in FINCH, for processing wide-bandwidth light sources, was done by inefficiently increasing the length of the systems. These difficulties were fruitfully solved in the later versions of FINCH; 19,21,24 some of them are reviewed in Sec. 2.2.…”

“…This is because the maximal OPD between two interfering waves becomes shorter as the two image points, generated by focusing the two spherical waves, get closer to each other. 24 Another characteristic feature of the dual lens SAFE, 64 in contrast to its previous iterations, is that the recorded subholograms are not stitched together along the central x, y axes of the final mosaic hologram. This guideline yields better results because most of the energy emitted from commonly observed objects propagate toward the system in a relatively small angle, thus, any stitch between subholograms that passes through the central area (where most of the light concentrates) might distort the reconstructed image.…”

Abstract. Today, spatial light modulators (SLMs) offer the world of digital holography a robust technology that can be incorporated into hologram recorders. This review surveys recent developments related to the role of SLMs in a family of incoherent digital hologram recorders termed Fresnel incoherent correlation holography (FINCH). Two systems branching out from FINCH, and discussed herein, are a confocal version of FINCH and a synthetic aperture FINCH-based system.

We propose an alternative and simple solution to self-referenced digital holographic imaging based on a ring-shaped bifocal lens, without the need of any mirrors, polarizers or spatial light modulators. We discuss the imaging properties of the ring-shaped bifocal lens in self-referenced holography. The easy applicability of this bifocal lens is demonstrated on a realized microscope setup for volumetric observation of freely moving fluorescent objects, based on a conventional light microscope.

We present a new method for recording digital Fourier holograms under incoherent illumination. A single exposure recorded by a digital camera is sufficient to record a real-valued hologram that encodes the complete three-dimensional properties of an object. © 2012 Optical Society of America OCIS codes: 090.0090, 090.1995, 110.6880, 100.3010, 070.6120. In recent years we have witnessed noteworthy achievements of incoherent holography techniques such as optical scanning holography [1] and Fresnel incoherent correlation holography (FINCH) [2,3]. The latter has fundamental system robustness since it is based on a single channel incoherent interferometer and because it does not require any scanning or mechanical movement. However, though a single FINCH image contains the complete three-dimensional (3D) information of an object, at least three images are required to solve the twin image problem [4]. In this Letter, we present a new method for recording digital Fourier holograms under incoherent illumination. Fourier holograms [5,6] possess some advantages over Fresnel holograms including, but not limited to, increased space-bandwidth product performance [7,8] and the relatively easy ability to process and manipulate the hologram, since it is captured in the spatial frequency domain. In addition, the hologram is more robust to information loss, as each object point is distributed over the entire hologram plane. Moreover, by recording a Fourier hologram of a half plane (or space), the twin image problem is avoided and the object can be reconstructed from a single exposure. Still, the proposed method maintains many other advantageous characteristics of FINCH [9]. We coin our method Fourier incoherent single channel holography (FISCH). The FISCH system is shown in Fig. 1. A white-light source illuminates a 3D object. Light scattered from the object passes through a band pass filter (BPF), becomes partially temporally coherent, and continues to propagate through a single channel incoherent interferometer. Eventually, interference patterns are captured by the CCD. Consider a point source object of complex amplitude A s positioned at the coordinate x s ; y s ; z s , a distance z s from the lens L 0 . A tilted diverging spherical wave of the form Tx; y; ⃗r s ; z s A s c ⃗r s ; z s L−⃗r s ∕ z s Q1 ∕ z s is induced over the L 0 plane, where ⃗ r s x s ; y s , c ⃗ r s ; z s is a complex valued constant dependent on the position of the point source, and L⃗ s expi2πλ −1 s x x s y y and Qs expiπsλ −1 x 2 y 2 are the linear and the quadratic phase functions, respectively, in which λ is defined as the central wavelength. A diffractive optical element of the form Q−1 ∕ f 1 is displayed on the spatial light modulator (SLM), positioned at a small angle relative to the optical axis. The SLM is polarization sensitive, so by introducing the linear polarizer P1 the single channel optical apparatus is effectively split into two beams (see [10] for a detailed explanation). With one beam the SLM functions as a converging diffractive lens wi...
