Abstract: An apparatus and method of registering a panel is disclosed. The panel is held in a frame. The frame includes a transparent plate that covers the panel. The transparent plate has a pattern on at least one surface. Next, an image of each one of a number of registration targets on the surface of the panel is received. The image is received through the transparent panel. The actual location of each one of the registration targets relative to the pattern is then determined.

Abstract: A system, method and article of manufacture is disclosed that provides an improved, more efficient, laser beam modulator and splitter. The combined device includes a crystal with a horizontal cross-sectional shape of a pentagon. The crystal includes a top surface, a bottom surface, and a first through fifth sides. The first side and the second side are substantially parallel. An absorber is mounted on the third side. The fourth and fifth sides are substantially opposite to the third side. The fourth and fifth sides form an angle substantially equal to 180 degrees minus the sum of a first a second Bragg angles. The crystal also includes at least one layer. For one embodiment, each layer includes an incident window on the first side, an active window on the second side and a transparent axis between the incident window and the active window. A first and a second transducer are mounted on the fourth and fifth sides.
