摘要： A plurality of light detector pairs are spaced around the emitter end of a surgical laser handpiece with different, converging directivities to sense pilot beam reflections from a target. Their differentially compared outputs are applied to a distance determining unit having an adjustable threshold or majority decision level to detect when the end of the handpiece is at a desired distance from the target, whereupon the main laser beam is activated. Such a majority distance determination reduces activation errors due to the reflective characteristics and contours of the target surface and the angle of the handpiece.
