Abstract:
An image processing apparatus and method for detecting a position of a rotating optical fiber is provided. The apparatus includes at least one rotating optical fiber that rotates about an axis of rotation and that emits light towards a surface and at least two stationary fibers for transmitting light reflected from a surface, each of the at least two stationary fibers having a known predetermined position relative to each other and to the axis of rotation of the at least one rotating optical fiber. At least one detector is configured to detect an intensity of light transmitted through each of the at least two stationary fibers within a given time interval and at least one calculator is configured to use the detected intensities and the known predetermined positions of each of the at least two stationary fibers to determine a relative angular position of the rotating optical fiber with respect to the at least two stationary fibers.
