MASS SPECTROMETRY BASED QUANTITATIVE ASSAYS

Not Available This proposed Phase I effort is directed towards development of a new speckle position displacement sensor to be used as a navigation sensor for military operations in an urban environment in areas where GPS signals are not available (e.g., buildings, tunnels, forested areas and high Electronic Counter Measure (ECM) environments). The proposed sensor would track the relative motion of a platform with respect to the ground. The proposed sensor is of a non-contact optical type, suitable for use by a dismounted soldier and/or a robotic system. A portable navigation platform would use two speckle position displacement sensors and a micromachined Coriolis gyro as an azimuth reference to measure the relative motion of the platform. In an alternate configuration, an additional speckle position displacement sensor can be utilized to provide the required azimuth reference. The new speckle position displacement sensor uses optical diffraction from an infrared diode laser to measure position and velocity. The new speckle position displacement sensor is based on an earlier precision non-contact velocimeter, which was developed under contract with U.S. Army Engineers Topographic Laboratories for application in precision land vehicle navigation in the Position and Azimuth Determining System (PADS). BENEFITS: Broad commercial applications are envisioned for navigation in situations where GPS is not available such as tunnels and underpasses. The high accuracy of the proposed system
