Micro actuator for fiber

Prototype of single optical fiber actuator for large (1000+) arrays to intercept individual star/galaxy images in telescope image plane for spectroscopy analysis. Each actuator covers a 19mm hexagonal area and can move the fiber in that area without interferring with neighboring actuators using R-Theta axis arrangement controlled by miniature stepper gearmotors. Only radial axis shown […]
