What in the heck is this? Deft Laboratories Image Processing Module
 

Got this from a ham radio guy in my neighborhood who’d passed a couple months ago. I’ve dug it up and I wanna decide what to do with it. I have no idea how it’s supposed to work.

Only info I can really find is this -> https://ntrs.nasa.gov/citations/19810053344

I discovered a paper that seems to describe work on this device for the Department of Defense:

It has somethnig to do with two-dimensional Fourier transforms of infrared images.

DEFT stands for Direct Electronic Fourier Transform.
