Beam Launch and Imaging System (BLIS). The BLIS sub-system will be installed at the top of a five-story test for measurement of an M1 segment assembly below at the bottom of the tower. The side covers have been removed in the picture on the left, showing the mechanical setup and cable routing of the imaging and illumination system. At center, the access door allows the technician to exchange the computer-generated hologram (CGH) to match the type of M1 segment that is being measured.
