Terahertz spectroscopy and imaging in dynamic environments

Embodiments are disclosed for terahertz spectroscopy and imaging in dynamic environments. In an embodiment, a transmitter of an electronic device emits a continuous electromagnetic (EM) wave in the terahertz (THz) frequency band into a dynamic environment that includes a transmission medium that changes over time. A receiver of the electronic device, receives an EM wave reflected off an object in the environment and determines a spectral response of the reflected EM wave. The spectral response includes absorption spectra at a frequency in the THz frequency band that is indicative of a known target transmission medium. The absorption spectra of the target transmission medium and a path length of the reflected EM wave signal are used to obtain the concentration level of the target transmission medium from a reference library of known concentration levels.

Foreign substance inspection apparatus and foreign substance inspection method

Apparatus inspects the presence/absence of foreign substance on object having inspection region and non-inspection region arranged outside the inspection region. The apparatus includes sensor for illuminating the object and output, as image, result acquired by detecting light from region including the inspection region, and processor for detecting foreign substance based on inspection region image acquired by excluding non-inspection region image, which is image of the non-inspection region, from the image output from the sensor. The non-inspection region image includes first part generated by light from predetermined part of the non-inspection region of the inspected object and second part whose pixel value is continuous from pixel value of the first part and the processor specifies the second part based on fact that the pixel value of the second part is continuous from that of the first part.
