  • Innovative Beam Design for Fiber Laser Accelerometer Vector & Pressure Sensors | TechLink
    axis sensitivity from the orthogonal direction The crux of the design is a series of lever arm flappers inclined at approximately 45 degrees Vertical acceleration causes the inertial mass of the flappers to bend downward and inward relieving the strain on the center bridge and the fiber at that position Connecting a fiber laser to this rigid low mass lever arm design enables the fiber laser to experience greater displacement than the center of mass The result is increasing sensitivity to bandwidth tradeoff The innovative lever arm transducer was fabricated from a photopolymer by photolithography for use in 5 and 10 kHz erbium fiber laser sensor designs Sensitivity at the hundreds of femtostrain level has been achieved Additional improvements are anticipated with further design modification and material optimization The sensor device represents an inexpensive approach to high sensitivity on a single axis Utilizing a second device in a different orientation can create a system that accurately measures movement in both axes Multiple sensors can be strung together and multiplexed to enable longer devices Benefits Highly Sensitive The innovative lever arm flappers have demonstrated sensitivity at the hundreds of femtostrain level with the potential for even better performance with further design

  • Shoreline Extraction Algorithm | TechLink
    an algorithm and software to quickly and easily extract shoreline data from remotely sensed imagery The Navy s innovative approach extracts water and non water point pixels and employs a unique interrelation between the two in order to generate highly accurate boundaries that are properly ordered and oriented for GIS applications The system determines water non water points by calculating the entropy or roughness in the image This approach requires only a single channel image of sufficiently high resolution and positional accuracy for the desired result there are no a priori requirements of image format size color space or sensor used Edge points identified at the water land interface are then properly ordered and oriented by creating three point segments with normal vectors pointing into the center of the river Proper order is then calculated resulting in open segments and closed loops for islands within the channel and lakes outside that are quite insensitive to image noise User defined settings fine tune the threshold for noise tolerance and the inclusion exclusion of smaller lakes puddles and islands Benefits Accurate The innovative combination of edge and water pixels determined by entropy and using those points together to properly orient each edge point typically results in a root mean square deviation less than twice as large as the ground sample distance of the imagery Image Agnostic Requires only a single channel image in any georeferenced format and from any sensor source with sufficient resolution for the desired output Simple and Tunable The technique does not require pre or post processing but the user can specify up to three parameters to refine the sensitivity and resolution of the output The Opportunity Available for license US patent 8 238 658 US patent 8 542 924 US patent 9 008 441 Potential for collaboration with

  • Sun Glint Correction for Shallow Water, High Resolution, and WorldView-2 and WorldView-3 Imagery | TechLink
    The original uncorrected image is above left The Technology The US Naval Research Laboratory NRL has developed and tested a patent pending algorithm and software to correct remotely sensed imagery for specular reflection also known as sun glint The NRL technique offers three key benefits The first is the ability to accurately correct for glint in shallow water locations where the bottom contributes to reflection in a manner that most traditional correction methods cannot accurately handle The second is the ability to compensate for specular reflection before or after atmospheric correction techniques using sensor radiance spectra to estimate atmospheric variable parameters may result in incorrect or inconsistent removal of the atmospheric component of the signal in glinted areas The final benefit specific to imagery from the WorldView 2 and WorldView 3 sensors is the ability to effectively correct images while taking into consideration the 0 2 second time gap between data collection for the two 4 band multi spectral arrays The NRL de glinting algorithm employs a moving window approach to calculate the glint contribution for each pixel in the image This technique is ideal for high resolution and broad range radiometric in imagery because it processes each 4 band array individually and utilizes the data in the local area to provide the baseline NIR reflectance rather than using a single whole image relationship Benefits Effective in Shallow Water Preserves non zero NIR reflectance in shallow water areas in order to accurately correct for glint under circumstances where traditional methods fail Flexible Can be applied before or after atmospheric correction in order to maintain de glinting effectiveness especially for high spatial resolution radiometrically broad collections Simple De glinting is automated following masking for land masses clouds and cloud shadows The Opportunity A pending US patent filing and software code are
