A MATLAB program for 2D particle tracking or 3D DHM based tracking.
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 fix & Blob detection functions.

Routines for wavefront propagation in IDL, Matlab, and Python
PROPER is a library of routines for the propagation of wavefronts through an optical system using Fourier-based methods. It was developed at the Jet Propulsion Laboratory for modeling stellar coronagraphs, but it can be applied to other optical systems were diffraction propagation is of concern. It is currently available for IDL (Interactive Data Language), Matlab and Python (2.7 & 3.x). It includes routines for generating complex apertures and obscurations and aberrations (Zernike & PSD-defined). It includes a model of a deformable mirror for wavefront control. The routines perform near and far field propagation with automatic selection of propagators. The latest version for IDL and Python is v3.0 released on 7 Aug 2017. For Matlab it is v3.0.1 released on 22 Aug 2017 (bug fix in prop_readmap).
A MATLAB toolbox to simulate optical systems
Modal Interferometer Simulation Tool (MIST) is a MATLAB toolbox that can simulate arbitrary resonant optical systems in the paraxial beam approximation. It allows the user to define any optical setup (composed typically of laser sources, mirrors, lenses, electro-optical modulators and detectors) and to compute the static laser field at any point. It uses a Hermite-Gauss modal decomposition to simulate diffraction limited optics. This tool is being developed mainly for simulation of large scale interferometers with resonant cavities used for the detection of gravitational waves. Subscribe to the mailing list for updates and news. If you use MIST in your own simulation work, please cite is as G.

Scanning Probe Image Wizard - MATLAB Toolbox
SPIW is a MATLAB toolbox, for automated processing of scanning probe microscope images. Tools are applicable to all SPM images, but the main focus is on images with atomic or molecular resolution. SPIW is primarily a MATLAB toolbox with functions designed to be called in a user's own script. SPIW also has a very basic GUI for browsing and exporting images. For information on SPIW's performance see our publication ( http://dx.doi.org/10.1063/1.4827076 ) in the Review of Scientific Instruments. A related open-source project SPIEPy (https://pypi.python.org/pypi/SPIEPy/) is developing a python library to for automated SPM imaged enhancement. SPIEPy brings many SPIW algorithms to the Python user.
Spectroradiometer control for shipborne reflectance measurements
Spectroradiometer control for autonomous reflectance measurements from moving vessels. The software incorporates GPS signal parsing, control of the sensor platform viewing angle (stepper motor control), sensor triggering and data recording. Continue to the download section for the latest release information Rrs data processing code (the 'fingerprint technique') is also available - but moved to my github page: https://github.com/StefanSimis -------- Oct 2014: a beta version is available (20141006) Sep 2014 news: The latest version is 20140723, addressing some bugs. See the change log. Enjoy! Two Rflex units collected over 30,000 validated Rrs spectra on the Baltic Sea this year! See http://www.ferryscope.org for dissemination of these results in the coming years. ------ Licence: http://creativecommons.org/licenses/by-nc-sa/3.0/
