A live print scanner includes a transparent tray platen apparatus and a scanning system. The transparent tray platen apparatus includes a base region attached to two rounded side regions. The base region of the tray platen assembly includes a convex portion. A hand is placed atop the base region adjacent to one of the two rounded side regions such that the hand's palm pocket is atop the convex portion. A sensor assembly within the rotary scanning system generates a complete image of a palm print pattern. Because of the side regions and the convex portion, the image generated includes an image of a print pattern on the palm pocket as well as on the side of the palm. A holographic element may be disposed in a light path between an illumination source and the sensor.
