Laser pattern hologram

Custom Jelly and Marshmallows laser pattern generator.

A while back I saw a link to CorticalCafe’s page on printing your own holograms using a domestic 600dpi printer. But when looking for options for my 4f correlator I came across a much higher resolution low cost printing approach; there are online services that print 35mm projector slides at 4K resolution. That works out at about 2800dpi!

I used the CGH program to make some holograms to make some laser patterns, and they worked really well…
