Abstract
A method of calibrating the intensity with which light is emitted through the light-emission face of an optical fiber light line assembly employs (i) a data processing system with computer memory, (ii) a camera communicatively linked to the data processing system, and (iii) a signal-responsive scoring device communicatively linked to the data processing system. Light is introduced into the assembly, an image of the emitting face is captured, and corresponding image data is stored in computer memory. The image data is segmented into plural image-data segments corresponding to physical sub-regions of the imaged face. The image-data segments are algorithmically analyzed to identify the sub-region that emits inputted light with the lowest intensity, and emission-intensity data associated with that sub-region is identified as reference emission data. Comparative analysis of the image-data segments identifies “non-compliant” sub-regions that emit light with unacceptably high intensity in accordance with a pre-established parameter set. The data processing system issues scoring signals that cause the scoring device to score each non-compliant sub-region until that sub-region emits light w…
