Abstract:
The present disclosure provides an apparatus for generating fiber delivered laser-induced dynamically controlled white light emission. The apparatus includes a laser diode unit for generating a laser electromagnetic radiation with a blue emission in a range from 395 nm to 490 nm that is delivered by an optical fiber. The apparatus further includes a dynamic phosphor unit configured to receive the laser exited from the optical fiber and controllably deflect a beam focused by a first optics sub-unit to a surface spot on a phosphor plate to produce a white light emission. Additionally, and the dynamic phosphor unit includes a second optics sub-unit configured to collect the white light emission and to project to a far field. Furthermore, the apparatus includes an electronics control unit comprising a laser diode driver and a MEMS driver for respectively control the laser diode unit and the dynamic phosphor unit in mutually synchronized manner.
