OPTICAL PROBE USING MULTIMODE OPTICAL WAVEGUIDE AND PROXIMAL PROCESSING

Title:

OPTICAL PROBE USING MULTIMODE OPTICAL WAVEGUIDE AND PROXIMAL PROCESSING

Document Type and Number:

WIPO Patent Application WO/2019/140144

Kind Code:

A1

Abstract:

An optical source that generates an optical beam that propagates from a proximal end to a distal end of an optical fiber that imparts a transformation of a spatial profile of the optical beam. An optical control device imparts a compensating spatial profile on the optical beam in response to a control signal from a signal processor. A distal optical source generates a calibration light that propagates through the one or more optical waveguides from the distal end to the proximal end of the optical fiber. An optical detector detects the calibration light and generates electrical signals in response to the detected calibration light the signal processor generates the control signal to instruct the optical control device to impart the compensating spatial profile on the optical beam that at least partially compensates for the transformation of the spatial profile of the optical beam imparted by the optical fiber.
