Tomographic Scanning Imaging Seeker
The tomographic scanning (TOSCA) imaging seeker concept is presented. The system is based on conical scan reticle seeker optics modified with an eccentrically rotating circular aperture. After signal preprocessing, an image is extracted using tomography reconstruction techniques. Simulation results are provided to show the reconstruction quality. The concept, using a single pixel and a simple r...
متن کاملVariable tomographic scanning with wavelength scanning digital interference holography
We present a new method for variable tomographic scanning based on the wavelength scanning digital interference holography (WSDIH). A series of holograms are generated with a range of scanned wavelengths. The object field is reconstructed in a number of selected tilted planes from each hologram, and the numerical superposition of all the tilted object fields results in a variable tomographic sc...
متن کاملExcessive thoracic computed tomographic scanning in sarcoidosis.
BACKGROUND The clinical value of computed tomographic (CT) scanning of the chest in the initial assessment of sarcoidosis was investigated. METHODS One hundred consecutive patients referred to the sarcoidosis outpatient services of the Mount Sinai Medical Center, New York from 1990 to 1992 with a presumptive diagnosis of sarcoidosis were studied. The diagnosis was subsequently confirmed in al...

متن کاملScanning Tomographic Acoustic Microscopy with Multiple Transducers and Frequencies
The scanning tomographic acoustic microscope (STAM) is an instrument that utilizes the principles of diffraction tomography and acoustical holography to produce unambiguous subsurface images of structurally complex objects. One of the several techniques to obtain projection data is to rotate the transducer and another, to rotate the specimen. In either case a small unknown movement out of regis...
