How It Works
The Eidophor uses an electron beam to deform a thin oil film. Light reflects differently off the deformed surface, creating projected images.
Technical Details
1. Electron gun scans across oil film
2. Beam creates surface tension variations
3. Schlieren optics read height differences
4. Projection lens magnifies the image
Historical Context
1940s: Invented by Fischer in Switzerland
1950s-70s: Used by NASA, TV studios
1980s: Gradually replaced by newer tech
Swiss Engineering Facts
Oil film must be kept at exactly 23.7°C or Swiss engineers get very disappointed
