  • High Resolution, Large Field of View, Long Working Distance Microscope at a Fraction of Existing Cost | TechLink
    a spatial filter s f filter with a preformed pinhole used in optics to take out noise as a point source to pick up aberrations as it travels through the optical system Fig 1a By recording this error holographically it is automatically corrected for when the hologram is reconstructed with the same point source Fig 1b Object features near or at this point are imaged with little or no aberration Fig 1c Figs 1a 1b can be done in the factory and 1c in the field by the user Slight modifications to Fig 1 will result in a reflecting microscope The operating principles encompassed by this invention are applicable across most of the electromagnetic spectrum of interest for microscopy from x ray to infrared Benefits Holographic correction Resolution performance equivalent to objective lenses that cost much much more than the imperfect lenses mirrors that can be used here Long working distances Flexible viewing condition including in situ real time observations Large field of view Ease of operation no longer necessary to toggle lenses of different magnifications or stitching various scenes together to get the full picture Demagnification and photoreduction The system can be used in reverse to project a demagnified

  • Network Geo-location Technology | TechLink
    the user claims as his her location NGT is based on the laws of physics and operates independent of an IP address look up or any other pre existing user network address profiles NGT uses the latency of communications to and from an address to determine its location In order to do this a network latency topology map is created based on the latency between multiple network stations and known network endpoints The system is especially useful for determining if a user is actually at the location he she claims There are a number of commercial services that report the physical location for an Internet IP address by looking up the address in a proprietary database Such systems will not scale well when the Internet moves from IP version 4 with 32 bits of address space to IP version 6 with 128 bits NGT will not be affected by the IPv4 to IPv6 migration Benefits Robustness The NGT system is difficult to spoof Certainty When NGT gives a location it is accurate The system might not be able to confirm a location fix and return a false negative but it will not generate a false positive Not affected by change

  • Hybrid Lidar-Radar for Medical Diagnostics | TechLink
    created by the tissue itself The Navy system utilizes continuous wave light that is preferably modulated at frequencies up to 60 GHz The present invention filters the return signals from the tissue at a subcarrier modulation frequency so as to reject erroneous information contained in scattered light while at the same time retaining the coherent unscattered and modulated light information to provide accurate detection of objects within tissues The noninvasive and early detection of biological tissue abnormalities with submillimeter dimensions such as tumors is an important challenge X ray and ultrasound techniques lack the resolution to detect such small objects Magnetic resonance imaging MRI has submillimeter resolution but is too costly for general use There is a need for high resolution medical imaging at a reasonable cost Benefits Safe and Noninvasive Does not expose the patient to the ionizing radiation of an x ray High Resolution Can detect small anomalies leading to earlier diagnosis and improved prognosis Low Cost Much less costly than current high resolution technologies The Opportunity US patent 7 010 339 is available for license Further joint development with the Navy is possible under a Cooperative Research and Development Agreement CRADA Additional details of the technology an
