Compressive coded aperture imaging
Nonlinear image reconstruction based upon sparse representations of images has recently received widespread attention with the emerging framework of compressed sensing (CS). This theory indicates that, when feasible, judicious selection of the type of distortion induced by measurement systems may dramatically improve our ability to perform image reconstruction. However, applying compressed sens...
متن کاملCoded aperture compressive temporal imaging
We use mechanical translation of a coded aperture for code division multiple access compression of video. We discuss the compressed video's temporal resolution and present experimental results for reconstructions of > 10 frames of temporal data per coded snapshot.
متن کاملCoALA-SPECT: a coded aperture laboratory animal SPECT system for pre clinical imaging
We have previously demonstrated the potential of multi-pinhole coded apertures when used in conjunction with compact pixelated detectors for high resolution, high sensitivity small animal SPECT. We are now constructing a prototype SPECT system with three such detectors mounted on a rotating gantry. Each detector comprises a 12 cm diameter circular array of NaI(Tl) crystals, each 1x1x5 mm3 on a ...
متن کاملComputational Photography: Coded Exposure and Coded Aperture Imaging
The emerging field of computational photography is exploring the possibilities of digital photography beyond the imitation of film cameras. Novel illumination, optics, sensors, and processing methods are employed to expand the set of images that cameras can create. This thesis introduces the field of computational photography and presents two exemplary techniques that address the problem of blu...
متن کاملImprovements in coded aperture thermal neutron imaging
A new thermal neutron imaging system has been constructed, based on a 20-cm x 17-cm He-3 position-sensitive detector with spatial resolution better than 1 mm. New compact custom-designed position-decoding electronics are employed, as well as high-precision cadmium masks with Modified Uniformly Redundant Array patterns. Fast Fourier Transform algorithms are incorporated into the deconvolution so...
