Photograph of a rat positioned in the setup. Rat, Indentation and MRE component are indicated with arrows. In A, the indentor, put through the surface RF coil, positioned on top of TA muscle in rats hindleg, and the MRE piston attached at distal side of TA muscle are shown. Indentation component is removed in B, revealing the MRE component and surface coil. Pre-amplifier block of the surface coil, the respiratory sensor and the rectal temperature probe are also visible. Anesthesia mask and rat’s head are underneath the pre-amplifier block. (TIF)

Hierarchical structural matching algorithms for registration of aerospace images

February 2004 · Proceedings of SPIE - The International Society for Optical Engineering

The aim of investigation was developing the image registration algorithms dealing with the aerial and cosmic pictures taken in different seasons from differing view points, or formed by differing kinds of sensors (visible, IR, SAR). The task could not be solved using the traditional correlation based approaches, thus we chose the structural juxtaposition of the stable specific details of pictures ... [Show full abstract] as the general image matching technique. Structural matching was usually applied in the expert systems where the rather reliable results were based on the target specific algorithms, but our algorithms deal with the aerospace photographs of arbitrary contents for which the application specific approaches could not be used. The chosen form of structural descriptions should provide distinguishing between the similar simple elements in the huge multitudes of image contours, thus the descriptions were made hierarchical: we grouped the contour elements belonging to the separate compact image regions. The structural matching was carried out in two levels: matching the simple elements of every group in the first image with the ones of every group in the second image; matching the groups as the wholes. The top-down links were used to enhance the lower level matching using the higher level matching results.

At-wavelength inspection of sub- 40 nm defects in extreme ultraviolet lithography mask blank by phot...

June 2007 · Optics Letters

A new at-wavelength inspection technology to probe nanoscale defects buried underneath Mo ∕ Si multilayers on an extreme ultraviolet (EUV) lithography mask blank has been implemented using EUV photoemission electron microscopy (EUV-PEEM). EUV-PEEM images of programmed defect structures of various lateral and vertical sizes recorded at an ∼ 13.5 nm wavelength show that 35 nm wide and 4 nm high ... [Show full abstract] buried line defects are clearly detectable. The imaging technique proves to be sensitive to small phase jumps, enhancing the edge visibility of the phase defects, which is explained in terms of a standing wave enhanced image contrast at resonant EUV illumination.

Calibration of Advanced Visible and Near Infrared Radiometer (AVNIR)

December 1997 · Geocarto International

Initial on‐orbit calibration results of the advanced visible and near infrared radiometer (AVNIR) onboard ADEOS were presented. When ADEOS returned over the Japan ground station mask on Sept. 11996, AVNIR was first activated to evaluate performance. AVNIR calibration toas then conducted using the reference signal sources (internal lamps, natural target data, NASA's airborne sensor data, etc). The ... [Show full abstract] evaluation indicated that AVNIR has sufficient sensitivity to function as a high‐resolution imager and is useful for the land monitoring, though some noises are to be removed.

Electron density characterization by use of a broadband x-ray-compatible wave-front sensor

February 2003 · Optics Letters

The use of a Hartmann wave-front sensor to accurately measure the line-integrated electron density gradients formed in laser-produced and z-pinch plasma experiments is examined. This wave-front sensor may be used with a soft-x-ray laser as well as with incoherent line emission at multikilovolt x-ray energies. This diagnostic is significantly easier to use than interferometery and moiré ... [Show full abstract] deflectometry, both of which have been demonstrated with soft-x-ray lasers. This scheme is experimentally demonstrated in the visible region by use of a Shack–Hartmann wave-front sensor and a liquid-crystal spatial light modulator to simulate a phase profile that could occur when an x-ray probe passes through a plasma. The merits of using a Hartmann sensor include a wide dynamic range, broadband or low-coherence-length light capability, high x-ray efficiency, two-dimensional gradient determination, multiplexing capability, and experimental simplicity. Hartmann sensors could also be utilized for wavelength testing of extreme-ultraviolet lithography components and x-ray phase imaging of biological specimens.
