The Self-Orienting Imaging Device and Methods of Use sense the orientation of the handheld imaging, and apply the rotational correction by rotating the image to be displayed. When a scanner is used, the scanning element in the scanner is adjusted, such that the eventual scanning direction remains unchanged referencing the subject anatomy. The self-orienting mechanism for the scanner may be implemented in hardware mechanisms.

CALIBRATION APPARATUS AND METHOD FOR CALIBRATING OPTICAL SCANNING APPARATUS
20180003953 · 2018-01-04 · ·

This method is for calibrating an optical scanning apparatus that includes an optical fiber with a tip supported to allow vibration and an actuator that drives the tip of the optical fiber in a direction perpendicular to the optical axis of the optical fiber. The method includes arranging a position sensitive detector that detects a position of emitted light from the tip of the optical fiber (step S02) and detecting the position of the emitted light with the position sensitive detector while supplying light to the optical fiber and driving the tip of the optical fiber (step S03). The step of detecting (step S03) is performed using an interference fringe reducer that reduces interference fringes occurring along an optical path reaching the position sensitive detector.
