SCANNING LASER PROJECTION DISPLAY DEVICES AND METHODS FOR PROJECTING ONE OR MORE IMAGES ONTO A SURFACE WITH LIGHT-SCANNING OPTICAL FIBER

摘要

Image projection devices, high-speed fiber scanned displays and related methods for projecting an image onto a surface and interfacing with the projected image are provided. A method for projecting one or more images and obtaining feedback with an optical input-output assembly is provided. The input-output assembly comprising a light-scanning optical fiber and a sensor. The method includes generating a sequence of light in response to one or more image representations and a scan pattern of the optical fiber, articulating the optical fiber in the scan pattern, projecting the sequence of light from the articulated optical fiber, and generating a feedback signal with the sensor in response to reflections of the sequence of light.

1. A method for projecting one or more images onto a surface and obtaining feedback with an optical input-output assembly, the method comprising:
generating a sequence of light in response to one or more image representations and a scan pattern of an optical fiber; articulating the optical fiber in the scan pattern with a variable velocity; projecting the sequence of light from the optical fiber to form the one or more images on the surface, wherein a light intensity of the sequence of light is varied based on the variable velocity of the optical fiber; and generating a feedback signal with a sensor in response to reflections of the sequence of light.
