Fabry-Perot Simulator

07 Jun 2006 (Updated 29 Jun 2006)

Simulates intensity after propagation of Gaussian Beam through a Fabry Perot interferometer.

File Information
Description	This program simulates Gaussian beam propagation through a Fabry-Perot interferometer with adjustable error angles. The result is the intensity behind the cavity at a screen perpendicular to the propagation direction. It contains a GUI for setting the parameters and viewing the result.
MATLAB release	MATLAB 7.2 (R2006a)

09 Jun 2006	Birk Andreas	There is an error in version 1.0 that is fixed in version 1.1. I have it uploaded already. However, it may take a while until the new version is made available. If you can't wait, open the .m, go to line 241 and change it to "zd=zm+abstand*1/sqrt((tan(xim))^2+(tan(etam))^2+1);".
13 Jun 2006	Birk Andreas	Actual version is 1.2. Version 1.1 has an error in line 244 (change the 2nd "+" from left into "*"). I wonder how I could not see this earlier...

Updates
09 Jun 2006	1. Fixed an Error. 2. Now observation screen size is fixed to calculation window width
13 Jun 2006	1. Fixed another formula error (line 244) 2. Implemented export to workspace 3. Now with phase map (look into workspace)
29 Jun 2006	Now a ray's electric field is distributed over the nearest four pixels according to the respective covered area. Before the rays coordinates were rounded and therefore its field was put on only one pixel.
