We present a versatile and fast MATLAB program (UmUTracker) that automatically detects and tracks particles by analyzing long video sequences acquired by either light microscopy or digital holography microscopy (DHM). Our program finds the 2D particle center position using an isosceles triangle transform and the axial position by a fast implementation of Rayleigh-Sommerfeld numerical reconstruction algorithm using a one dimensional radial intensity profile. *Updates v1.1: 2017/11/21- Bug...

This program develops a model of the volume of the particles in the optically transparent medium. The volume is represented as a set of layers with equal distances maintained between them. Whereby these layers contain particles. The wavefront passing through the predetermined volume is thus scattered by the particles in each layer. Axial hologram is reconstructed by numerical back propagation of the wavefront to the first layer of volume. Further, two adjacent layers with particles are...

This is a tool set for controlling digital micromirror devices for creating digital holograms and general optical field patterns. Hardware requirements include a laser and a DMD development board. A description of the use of the software in digital holography can be found here: http://cops.nano-cops.com/publications/superpixel-based-spatial-amplitude-and-phase-modulation-using-digital-micromirror-devic This software was developed with support from ERC and FOM.

Software for the evaluation of x-ray holography data.

HoloController allows the automation of a holography lab by providing computer control of shutters, lasers, sensors and switches as well as the automation of final hologram exposure. The controller software is based off work done at http://holography.dra

Computational holography program. Generates diffraction patterns for 2-D images. My kindom for a laser printer than can print at half micron resolution.
