Webb1 mars 2024 · Key processing steps of THz micro-bolometer. Scanning electron microscope (SEM) characterization ( Fig. 7 a) reveals that the designed THz micro-bolometers with an array of 384 × 288 have been successfully fabricated. It is clear that the as-fabricated micro-bolometers are morphology integrity and their surfaces are smooth ( … WebbThe optical characteristics of a terahertz (THz) antenna-coupled bolometer (ACB) detector were evaluated using a pulsed quantum cascade laser (QCL) and radiation blackbody sources. We investigated a method for measuring the responsivity and noise-equivalent power (NEP) of the THz detector using two different types of light sources. When using a … myer new balance 624
