Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

C23C 1434

US Classification:

20419226, 20419212

Abstract:

Optical coatings and methods of fabricating the same. According to a preferred embodiment, the optical coatings comprise polymeric films formed from the disassociation of chemical products from a gaseous hydrocarbon in plasma. The disassociation process is performed in low-pressure environment and without radio frequency substrate bias. The resultant optical coatings have superior stability, durability and flexibility and may be utilized on highly flexible substrates. The coatings of the present invention can additionally be utilized for multi-layer optical designs and further, may be doped with a polar material to thus cause the coating to possess a desired index of refraction.

International Classification:

G06G007/48

US Classification:

703/006000

Abstract:

A multi-disciplinary method for design optimization includes developing a number of single-disciplinary modules, which are integrated into a multi-disciplinary module, and performing system level optimization and sensitivity analyses using the multi-disciplinary module. Each single-disciplinary module includes simulation code which can be run on a computer and interfaced with at least one input file and one output file. Developing single-disciplinary modules includes constructing a reusable component for each single-disciplinary module. The reusable component wraps the simulation code by file parsing the simulation code input and output files. By wrapping the simulation codes, the single-disciplinary modules can be interfaced by placing the reusable components for each single-disciplinary module in communication with each other. The reusable component also formulates a problem by defining objectives, constraints and knowledge rules, as well as selects one or more optimization algorithms. System level optimization can be performed by concurrently performing single-discipline analyses using the communicating single-disciplinary modules.

Assignee:

Northrop Corporation - Hawthorne CA

International Classification:

B05D 306

US Classification:

427 531

Abstract:

A laser or other light beam is directed onto an optical substrate while an optical coating is being vacuum deposited thereon. The laser has a wavelength at or near that at which a reduced absorptance of the coating is desired. In one embodiment, the substrate is heated electrically. Thin film optical coatings having a substantially lowered absorptance are made in this manner.

International Classification:

H01L 2144

US Classification:

437181

Abstract:

Methods are disclosed for making semiconductor windows which are transparent to light in the infrared range which have good electrical conductivity and are formed of a substrate material (11) having a semiconductor coating (14) having a dopant included therein. The coating is diffused, grown or deposited on one surface of the substrate and is controlled to obtain both low electrical resistivity and high infrared transmissivity. The coating can be formed of the same material as the substrate or can be a different material. Windows having particular thermal properties are formed utilizing zinc selenide and zinc sulfide as the substrate.

US Classification:

428623

Abstract:

A semiconductor window which is transparent to light in the infrared range and which has good electrical conductivity is formed with a substrate of semi-conductor material which has a conduction modifying dopant diffused, grown or deposited on one surface thereof to a substantial depth so that a layer thereof exhibits reduced resistance to a value below 10 ohms/square. Anti-reflection dielectric layers are stacked on both outer surfaces thereof. The dielectric substrate may be of silicon, germanium or gallium arsenide depending on the transparency bandwidth of interest. The thickness of the substrate and the doping of the surface thereof is closely controlled to obtain both low electrical resistivity and high optical transmissivity.

International Classification:

G01B 902

US Classification:

356360

Abstract:

A speckle pattern interferometer for use in the non-destructive testing of structures employs a laser beam which is split into reference and object beams having substantially the same optical path lengths to the screen of a sensor, such as a vidicon, where the two beams are combined. The object beam is reflected from the surface of an object under investigation, this object being vibrated periodically. The reference beam passes through an optical fiber cut to the proper length to equalize the length of the reference beam path with that of the object beam. The output of the vidicon is fed to an electronic processor where the signals are appropriately processed to provide a speckle pattern display on a monitor viewing screen.
