Powell Lens Equations for Gaussian to Flat Top Beam Conversion

AI Thread Summary
The discussion focuses on the conversion of a Gaussian beam into a flat top beam using a Powell lens, with a postgraduate student seeking equations related to beam parameters and lens characteristics. The student has found a patented document that provides the necessary relations and is interested in simulating the lens using ZEMAX software. Participants suggest utilizing ZEMAX's Part Designer or CAD software to create the lens model for simulation. Additional resources, including a thesis and links to optical modeling software, are shared to assist in the project. The conversation highlights the importance of understanding optical components in beam shaping applications.

I am a Post graduation student and I am doing a project on the conversion of a Gaussian beam into a flat top beam using optical components. I have found that the best component to do the same is a Powell lens. I would like to know more about the equations connecting the input beam diameter, output beam diameter, wavelength of the light and the fan angle of a Powell lens.

I don't know much about Powel Lenses, but i found this thesis discussing this kind of lenses, there are a few equations and simulations aswell.

Also, you can download the EDU version of OSLO optical modeling software and make a Powell lens in it and experiment how they work.

Thank you for your Reply.
I have already read the article but couldn't"find the relation from this one.
Still I am happy to tell you that I have got the relation from a Patented document.

Now that I have found the relation and working of the Powell lens, I would like to simulate it using ZEMAX optic studio software.
Can anyone please help me with the steps to be carried out in ZEMAX to generate a Powell lens and its properties.
 
You should post a thread at the Zemax General Discussion Forum: http://forum.zemax.com/Forum27.aspx

I don't know any simple method to simulate a powell lens in Zemax. You could try the Part Designer in Zemax to draw a Powell lens, or use a solid modelling CAD software (AutoCAD, Inventor, SolidEdge, SolidWorks etc.) to draw it, and then import it to Zemax.
 
Thread 'Simple math model for a Particle Image Velocimetry system'
Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...
