This research aims to design a new matching approach between terrestrial LiDAR (Light detection and Ranging) data and Synthetic Aperture Ladar (SAL) images. SAL is the extension of SAR (Synthetic Aperture Radar) to much shorter wavelengths, thus providing higher resolution. SAL acquires 2D images that are continuous representations of an environment during day and night times. LiDAR is commonly used...
The structural and morphological properties of the NdSr2RuCu2Oy (Nd1212) compound, which has been recently synthesized as a pure perovskite phase, are reported and compared with the properties of the magnetic superconducting triple perovskite GdSr2RuCu2O8 (Gd1212). The preparation of the RESr2RuCu2O8 (RE1212, RE = Rare Earth) phases is also critically reviewed and the nature of the magnetic ordering...
Video-rate THz reflection imaging, at 450 GHz using a high-resolution INO 384×288 pixel camera core, of pills in blister packs further contained within their final commercial packages is reported. These results open the door to deployable real-time THz cameras for see-through imaging applications, providing a tool for NDE quality control and security inspection of goods within their final packaging.
A THz VOx-based 160×120 microbolometer FPA camera with 52 μm pixel pitch has been developed at INO. Radiometric NEP values have been measured at different wavelengths. Real-time video-rate reflectance imaging using large beam area from a high-power FIR optically pumped THz laser has been also performed, demonstrating high sensitivity for stand alone applications.
Large area microbolometer detectors are very attractive for applications where high sensitivity is required. This is particularly important for long wavelength spectroscopy in the far-infrared and sub-millimeter region. This paper presents current progress in the development of large area uncooled microbolometer FPAs at INO.
A THz 160×120 pixel array camera has been developed at INO. Real-time transmission and reflectance imaging at video rates of 30 frames/s were performed with a low-power 3 THz quantum cascade laser. Various hidden objects were imaged, proving feasibility of real-time THz imaging for security screening applications.
INO has been actively working on extending its microbolometer technology to THz applications. Several techniques have been developed recently to improve the performance of the microbolometer. This article will present these techniques and discuss some potential applications of INO THz microbolometer.
This paper introduces a real-time compact optronic SAR processor that has the capability to generate ENVISAT/ASAR image swaths of 100 km × 100 km in 10 seconds exhibiting slant plane sampling distances of 4 meters in azimuth and 1 meter in range. It may be instantaneously reconfigured to process data from any of the 7 ASAR image swath modes. In this respect, numerous SAR image sets may be produced...
