Ka-Band Radar Terminal Descent Sensor
hot!
|
|
Date added: 10/01/2007 |
|
The Jet Propulsion Laboratory-developed radar altimeter/velocimeter improves the accuracy of
velocity sensing by more than an order of magnitude when compared to existing sensors. Further, the radar "terminal descent sensor" uses a millimeter-wave center frequency to
eliminate angle-of-arrival errors that can result in large velocity errors over inhomogeneous terrain. |

Improved Sensing Coils for SQUIDS
|
|
Date added: 10/01/2007 |
|
An immediate application of the suggested technique is to sense coils of low-field Magnetic Resonance Imaging systems, Magnetic Encephalography systems, and other similar biological magnetic probes. Immediate
sensitivity improvement of ~50% and corresponding two-fold imaging time reduction is possible in some configurations. |

WGM-Resonator/Tapered-Waveguide White-Light Sensor Optics
|
|
Date added: 10/01/2007 |
|
Searching for the compact sensors of high sensitivity led to gallery-mode-resonator (WGMR) based sensors. Resonator's usage takes fixed critical optical coupling, stable narrowband laser, mode locking. The Bessel beam technique removes all resonance related problems, conserving all advantages. |

Robust Mapping of Incoherent Fiber-Optic Bundles
|
|
Date added: 09/01/2007 |
|
A series of custom designed digital signal processing
algorithms is used to build a spatial transform matrix for real fiber position (incoherent) to virtual fiber position
(digital coherent imaging). These algorithms are integrated with a specific processing and visualization
computer processor. |

Photometric Calibration of Consumer Video Cameras
hot!
|
|
Date added: 09/01/2007 |
|
Consumer video cameras have not traditionally been useful for photometric measurements due to their limited dynamic range and non-linearity. This innovation overcomes the saturation (exceeding the dynamic range) of consumer video cameras by a combination of calibration hardware and algorithms. |
