Abstract:
An air sampler module is provided for use with a detection device that monitors liquids and/or solids on a surface using spectroscopy techniques. The air sampler module comprises a housing, an intake port for collecting air containing airborne threats to be analyzed by the detection device, and a port to permit communication of an optical transceiver of the detection device into the housing to permit analysis of the collected air. Thus, the capabilities of a spectroscopy detection system are expanded to include the ability to analyze airborne threats.
Modular Optical Detection System For Point Airborne And Area Surface Substance Detection

Assignee:
ITT Manufacturing Enterprises, Inc. - Wilmington DE
International Classification:
G01N 1/00 G01N 33/28 G01B 11/16 G01J 3/40
US Classification:
356 73, 356 32, 356302
Abstract:
A detection system and method are provided having vehicle-mounted and manportable mobile surveillance capabilities with minimal equipment redundancy. The system comprises a vehicle-mounted sensor unit, a hand-held unit, a manportable unit and a vehicle-mounted air collector unit. The vehicle-mounted sensor unit comprises a spectroscopy subsystem that is configured to direct light onto a surface outside the vehicle and to capture scattered optical energy from the surface outside the vehicle while the vehicle is moving. The hand-held unit may be removably mounted to the air collector unit to interrogate airborne particles in collected air. The hand-held unit is removable from the air collector unit and is connected to the manportable unit by a cable so as to form an integrated portable detection system for mobile surveillance away from the vehicle by a user.
Optical Modulation Utilizing Structures Including Metamaterials

ITT CORPORATION - McLean VA
International Classification:
H04B 10/04 G02F 1/01
US Classification:
398182, 359276
Abstract:
An optical modulation system includes a metamaterial structure configured to receive and process an input optical signal at at least one operational wavelength, where the metamaterial structure changes between a transmissive state and a non-transmissive state with respect to the optical signal(s) at the operational wavelength(s) in response to an external stimulus applied to the metamaterial structure. An external stimulus source is coupled with the metamaterial structure and is configured to change the metamaterial structure between its transmissive and non-transmissive states by applying selected stimulus pulses to the metamaterial structure. The optical modulation system processes the input optical signal to output a modulated optical signal that modulates in correspondence with the selected pulses applied to the metamaterial structure.
