  • Simultaneous Modulation Of Quantum Dot Photoluminescence Using Orthogonal Fluorescence Resonance Energy Transfer (Fret) And Charge Transfer Quenching (Ctq) | TechLink
    staff Patent Identifier 8921140 Status Active Categories Photonics Sensors Quantum dots are modified with varying amounts of a a redox active moiety effective to perform charge transfer quenching and b a fluorescent dye effective to perform fluorescence resonance energy transfer FRET so that the modified quantum dots have a plurality of photophysical properties The FRET and charge transfer pathways operate independently providing for two channels of control for varying luminescence

  • Nodding Mechanism For A Single-Scan Sensor | TechLink
    patent and related research and licensing opportunities please contact any of our Tech Managers at http techlinkcenter org about staff Patent Identifier 8909375 Status Active Categories Photonics Sensors A single scanning system for a robot can include a base and a nodding mechanism that pivotably attached to the base A single scan sensor such as a lidar or laser sensor can be fixed to the nodding mechanism and a controller can be connected to the single scan sensor and motor via a gear arrangement The controller can manipulate nodding characteristics such as nodding range and nodding angular velocity dynamically during operation of the robot either in response to a command from a remote user robot autonomy system or according to written instructions included in the controller An encoder disk can interconnect the nodding mechanism to the controller With this configuration the encoder disk can receive sensor data from the single scan sensor for further transmission to said controller A transceiver can route sensor data to the remote user and can also receive commands from the remote user USPTO url http patft uspto gov netacgi nph Parser patentnumber 8909375 Facebook Twitter Google Plus LinkedIn Main menu Home Licensing Joint R D

  • Method For Atmospheric Laser Beam Detection Using Remote Sensing Of Off-Axis Scattering | TechLink
    more about this patent and related research and licensing opportunities please contact any of our Tech Managers at http techlinkcenter org about staff Patent Identifier 8908178 Status Active Categories Photonics Sensors A method involves obtaining a first beam image on a focal plane of a first camera and a second beam image on a focal plane of a second camera from light scattered by ambient atmospheric aerosols in the path of a laser beam First and second projected beam images are formed representing the respective first and second beam images in the projected scenes of the respective first and second cameras First and second ambiguity planes are then formed from the respective first and second projected beam images An intersection of the first and second ambiguity planes is then determined identifying the position of the laser beam A source of the laser beam is then determined along with a camera source plane A beam elevation angle with respect to this plane is then determined as well as beam azimuth angles with respect to lines between the respective camera and the source USPTO url http patft uspto gov netacgi nph Parser patentnumber 8908178 Facebook Twitter Google Plus LinkedIn Main menu Home

  • Extended Source Wavefront Sensor Through Optical Correlation With A Change In Centroid Position Of Light Corresponding To A Magnitude Of Tip/tilt Aberration Of Optical Jitter | TechLink
    you are interested in learning more about this patent and related research and licensing opportunities please contact any of our Tech Managers at http techlinkcenter org about staff Patent Identifier 8907260 Status Active Categories Photonics Sensors An atmospheric aberration sensor that uses two optically correlated images of a scene and the Fourier transform capabilities of a lens or other focusing element The sensor receives light via an f number matching element from a scene or from an external optical system and transmits it through a focusing optical element to an updateable display element such as a spatial light modulator or micro mirror array which modulates the real time image from the focusing element with previous template image of the same extended scene The modulated image is focused onto an autocorrelation detection sensor which detects a change in centroid position corresponding to a change of the tip tilt in the optical path This peak shift is detected by centroid detection and corresponds to the magnitude of global wavefront tip tilt With a lenslet array and detector array the system can also measure local tip tilt and higher order aberrations USPTO url http patft uspto gov netacgi nph Parser patentnumber 8907260 Facebook
