Time-Resolved Technique Could Provide High Resolution for THz Imaging

Facebook X LinkedIn Email
Using a single-pixel camera operating at THz frequencies, researchers at the University of Sussex have discovered a way to capture with a high degree of accuracy not just the shape of an object, but also its chemical composition. The technique uses time-resolved measurement to reconstruct the complexity of an object. Time-resolved nonlinear ghost imaging. Courtesy of University of Sussex/ACS Photonics. The Sussex team’s approach was to illuminate an object with patterns of THz light containing a broad spectrum of colors. The team then used a single-pixel camera to capture the...Read full article

    nonlinear optics
    Nonlinear optics is a branch of optics that studies the optical phenomena that occur when intense light interacts with a material and induces nonlinear responses. In contrast to linear optics, where the response of a material is directly proportional to the intensity of the incident light, nonlinear optics involves optical effects that are not linearly dependent on the input light intensity. These nonlinear effects become significant at high light intensities, such as those produced by...
    terahertz
    Terahertz (THz) refers to a unit of frequency in the electromagnetic spectrum, denoting waves with frequencies between 0.1 and 10 terahertz. One terahertz is equivalent to one trillion hertz, or cycles per second. The terahertz frequency range falls between the microwave and infrared regions of the electromagnetic spectrum. Key points about terahertz include: Frequency range: The terahertz range spans from approximately 0.1 terahertz (100 gigahertz) to 10 terahertz. This corresponds to...
    hyperspectral imaging
    Hyperspectral imaging is an advanced imaging technique that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging systems that record only a few spectral bands (such as red, green, and blue in visible light), hyperspectral imaging collects data in numerous contiguous bands, covering a wide range of wavelengths. This extended spectral coverage enables detailed analysis and characterization of materials based on their spectral signatures. Key...
