% Optical Tweezers Toolbox 1.2 % % Contents of this README file: % % 1. A warning! % 2. License % 3. Installation % 4. Getting started % 5. Miscellany % 6. References % % This README file is supplied as a text file (README.txt) % and as an m-file (README.m). % % Contact: timo@physics.uq.edu.au % % ============ % 1. A warning % ============ % % This release incorporates many of the previous bug fixes. However, as % always this is a work in progress and may contain bugs from the new code. % Bugs you discover may prevent the correct results from being obtained. % Let us know what you find. % % See Section 4 Getting started for some basics, % and check out the example files. Contact us if you can't figure % it out, and we'll provide what help we can. % % Anyway, check % http://www.physics.uq.edu.au/people/nieminen/software.html % or % http://www.physics.uq.edu.au/omg/Links.html % to see if a new version is out. % % We do not guarantee that results in all cases will be correct and disavow % any liability for any damages this code may inflict. However, please keep % us in the loop so that we can endeavour to fix any issues you experience. % % ========== % 2. License % ========== % % Copyright 2007-2012 The University of Queensland. % % This package and its component files are copyright 2007-2012 by % The University of Queensland. Not-for-profit re-distribution of % the unmodified complete package. % % The package may be used free-of-charge for research, teaching, % or personal use. If results obtained using the package are % published, the package should be appropriately referenced. % % =============== % 3. Installation % =============== % % The easy way: unzip all of the files into a directory, and work % in there. % % The better way: unzip all of the files into a directory, and add % that directory to your MATLAB path. This way, you can keep your % files separate from the package files. % % ================== % 4. Getting started % ================== % % (a) Read the paper (ott_preprint.pdf, available from website above). % Read the user Guide (ottug_1.2.pdf). It will outline the basic % operation of the toolbox. % % (b) Copy the examples to your working directory, and play with % them. Start with example_gaussian.m. % % (c) It's best to use length units of the wavelength in the trapping % medium, usually free-space wavelength/1.33. % % (d) The examples calculate the force and torque efficiencies. These are % the force and torque per photon, in photon units. To convert to % SI units: % force_SI = force_Q * n * P/c % torque_SI = torque_Q * P/w % where n is the refractive index of the surrounding medium, % P is the beam power in watts, % c is the speed of light in free space, % w is the angular optical frequency, in radians/s. % % ============= % 5. Miscellany % ============= % % Plans for the future? % (a) Make the package less user-unfriendly. A good start would be to % include automatic choice of Nmax. % (b) A cool GUI interface would be nice, but (a) and (b) are much % higher priorities. % (c) Add T-matrix routines for essentially arbitrary particles. % % Want to contribute? Feel free to do so, either in the form of code % or suggestions. If you contribute code, you'll need to assign % copyright to The University of Queensland. % % ============= % 6.
