Patent number: 6110401Abstract: A simple, fast, and reliable method and apparatus are provided for replicating a light shaping surface structure on a laminated surface of a relatively rigid substrate. More specifically, after the substrate is mounted on a table and a layer of epoxy is deposited between the substrate and a submaster to produce a layered structure, the layered structure is automatically compressed in a nip formed between the table and an outer surface of a rotating impression roller, thereby replicating the surface structure in the epoxy layer. The epoxy is then cured, and the submaster is separated from the substrate to leave a laminated structure having the light shaping surface structure on a surface thereof. Preferably, the submaster is wrapped around the impression roller, and the impression roller is rotated while the table is reciprocated linearly to compress the layered structure in the nip.Type: GrantFiled: August 24, 1998Date of Patent: August 29, 2000Assignee: Physical Optics CorporationInventors: Kang S.

Patent number: 4970521Abstract: A method for obtaining excitation errors of elements in an array antenna increases the element unit cell area in the aperture plane by reducing the size of the fundamental period in spectrum space. An element unit cell in the aperture plane is increased by appropriately selecting rows of elements to establish row sets. A polarity of near field measurements are made with the phase shift applied to the elements of one row set for each measurement and the spectrum for each row set is determined from the data of the plurality of measurements. This spectra is then utilized to determine the element excitation coefficients.Type: GrantFiled: October 18, 1989Date of Patent: November 13, 1990Assignee: Unisys CorporationInventor: Kang S. Lee
