Digital Holography at Shot Noise Level [PDF]
By a proper arrangement of a digital holography setup, that combines off-axis geometry with phase-shifting recording conditions, it is possible to reach the theoretical shot noise limit, in real-time experiments.We studied this limit, and we show that it

Holographic opto-fluidic microscopy. [PDF]
Over the last decade microfluidics has created a versatile platform that has significantly advanced the ways in which micro-scale organisms and objects are controlled, processed and investigated, by improving the cost, compactness and throughput aspects ...

Presented in this paper is the technique of formation of required laser intensity distribution on the target with a reduced speckle noise. The method is based on the use of modified Fourier hologram adapted to controlled phase modulators.

Experimental demonstration of holographic three-dimensional light shaping using a Gerchberg-Saxton algorithm [PDF]
We use a three-dimensional Gerchberg–Saxton algorithm (Shabtay (2003) Opt. Commun. 226 33) to calculate the Fourier-space representation of physically realizable light beams with arbitrarily shaped three-dimensional intensity distributions.

Spatio-temporal scanning modality for synthesizing interferograms and digital holograms
We investigate the spatio-temporal scanning of a single-pixel row for building up synthetic interferograms or digital holograms, shifted each other of a desired phase step. This unusual recording modality exploits the object movement to synthesize interferograms with extended Field of View and improved noise contrast.

Synthesizing Incoherent Digital Holograms with Reduced Number of Projections [PDF]
We present a method of recording digital Fourier holograms under incoherent illumination, using a significantly reduced number of observed perspective projections and a digital prediction of the middle projections. The method is demonstrated experimentally.

Synthesizing computer generated holograms with reduced number of perspective projections
We present an improved method for recording a synthesized Fourier hologram under incoherent white-light illumination. The advantage of the method is that the number of real projections needed for generating the hologram is significantly reduced. The new method, designated as synthetic projection holography, is demonstrated experimentally.
