Adaptive Optical Laser Beam Steering Through Endoscope For Laser Surgery In Kidney

Inventors: Peng Kevin Chen: Tatum Varut Tarin: Bryan L. Nelsen

Patent Number: 14/520,078

Abstract

A lightguide is configured to transmit a scanned and/or focused processing beam to a target. The processing beam has a wavefront amplitude and phase set by a spatial light modulator. Suitable wavefront characteristics are obtained based on portions of the processing beam returned to a detector through the lightguide. A beam path can be detected at a first, reduced power, and processing along the beam path performed at a second, higher optical power.
