Digital Holography simulation

Greetings,


I am trying to record an off-axis hologram of a USAF resolution target using the non-sequential mode environment. The end goal is to study the aberrations introduced by the various optics involved in a holographic experiment setup. The desired setup looks like the image below,


Is there a way to acheive this? I can set up the collimated laser beam, mirrors, beam splitters, and detector to capture the hologram interference pattern, but I do not know how to go about inserting the USAF target and simulating the light diffraction from it.                               


Thank you for your time.


-Jose

Use the Slide object to place a .BMP or .PNG bitmap in the beam.


In sequential mode there is the Optically Fabricated Hologram capability that may be better suited to this. Theree is a Slide surfce in sequential mode too.

Thank you for the response. So I have tried the slide object, but it seems that the light beam remains collimated after passing through the slide. Is there a way to simulate diffraction with it and explicitly have it be either the Fresnel of Fraunhofer variety?
