Light-Tracking Optical Device and Application to Light Concentration

摘要

An automatic optical coupling device that uses liquid to couple focused light into a light-guide is described. The liquid moves within a chamber or layer via the thermocapillary effect in order to automatically track and couple a moving spot of focused light. Also provided is the application of these coupling devices in an array feeding into a common light-guide, optical designs to improve the performance of these arrays, and the application of such arrays to light collection.
