AI Thread Summary
To determine the phase and amplitude of a 3D Gaussian beam after it propagates through a lens, one can use the principles of optical propagation and lens transformation. The incident beam's characteristics, including phase and amplitude, can be analyzed using the lens's transfer function. Applying the Fourier transform can simplify the calculation of the beam's propagation through the lens. Additionally, considering the angle of incidence relative to the optic axis is crucial for accurate results. Understanding these concepts is essential for effectively analyzing light behavior after lens interaction.

Hello,
Given a 3D gaussian beam incident on a lens at an angle relative to the optic axis, with phase and amplitude on the incident surface known, what is the simplest way to find the phase and the amplitude after propagation through the lens?

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...
