The technique of showing very small images on a larger screen using special equipment that magnifies them.
The scientist used microprojection to display the tiny details of the cells on a big screen.
Microprojection → It is formed from "micro-" (from Greek "mikros", meaning small) and "projection" (from Latin "proiectio", meaning throwing forward). The word describes a small projection or something that is thrown forward in a diminutive form.
Think of something that is 'small' ('micro-') being 'thrown forward' ('projection') — that's what microprojection means.
