摘要：
A hand scanner according to the invention may obtain an image of the hand and fingers including the bracelet crease/carpel delta area and palm surface regions up to the tips of the fingers using ultrasound measurement techniques. A hand scanner according to the invention may include a movable arcuate platen and an energy transducer. In a method according to the invention, the transducer may be moved back and forth while moving a platen surface in order to advance the hand and thereby produce a raster type scan image. In this manner, the image of the hand print may be collected as a raster image representative of the scanned surface of the friction ridge skin.
