Thank you. I have to double check with staff at the university because I am definitely a math brainlet (I'm ashamed of how bad my math GRE was, though my writing and analytical was 92nd and 98th percentile) but the class I took on technical collections of intelligence made me think you don't need to know the precise physics or chemistry behind imaging technology, just how it works/limitations/strengths. The mathematics that seem to be required are probability and statistics which I can work with.
