Fiber scanning display from Schowengerdt's patent
A fiber scanned display (FSD) is a type of display that uses a fiber optic wire and moves the end around with a laser shooting through it to form a visible image.[1]
It uses the same principle used in scanning fiber endoscopes.
As a research project, Brian Schowengerdt created one of these systems. It used a piezoelectric tube with quadrant-plated electrodes.[2]
The means by which the fiber optic wire can be changed from its center position include the following: using a patterned piezoelectric tube, a permanent magnet, an electromagnet, an electrostatic drive, or a sonic drive.[3]
The piezo tube can be for example a PT230 PT Piezo Scanner Tube from Physik Instrumente.
