The apparatus includes two strobe lights positioned within a hand-held housing. An optical interface within the housing directs a portion of the light generated by each light source into substantially parallel planes which are projected out of the opening of the housing at converging angles onto the surfaces to be measured. A camera within the housing captures the resulting image and generates a signal corresponding to the image. A signal processor which includes a frame grabber card processes the signal generated by the array of detectors to thereby calculate the amount of gap and mismatch between the surfaces being measured. | |
