WebNov 7, 2016 · Terahertz beam The THz beam was generated from a microwave signal using a frequency multiplier chain (WR1.5-AMC, Virginia Diodes). We estimate that the total … To obtain an image with a spatial modulator and some single-pixel detector the following is performed: a beam of radiation is patterned with a time-varying mask and the transmission (or reflection) is simultaneously recorded through an object with a single-element detector. Then knowledge of the temporal … See more Our modulation relies on controlling the conductivity of a material, however the angle of incidence onto the controlled material is also important. Liu et al., derived the Fresnel coefficients for an infinitely thin … See more The software part of the system needs to model the temporal response of the physical components and significantly improve the overall SNR preferably without needing long post-processing times. Least-squares fitting … See more The culmination of the ideas in this work, namely the modulation geometry, software processing and undersampling, pave the way for a rapid THz spectroscopic imaging system without … See more Undersampling techniques are often used in single-pixel imaging modalities to reduce the acquisition time. Compressed sensing35 is a technique used to reduce the number of measurements needed to image an object, i.e. … See more
