WebTOPTICA Photonics TOPTICA offers receivers for coherent and incoherent terahertz detection. Photoconductive antennas (i.e., coherent detectors) enable phase-sensitive measurements with a high dynamic range in both time-domain and frequency-domain applications. Schottky diodes (incoherent detectors) lend themselves to fast terahertz … WebComputed Tomography Pioneer of CT imaging technology OVERVIEW CT SYSTEMS GANTRIES DETECTORS PATIENT TABLES Detectors The brains of the CT system …
WebPhotoconductive Photodiodes. The Photoconductive Detector Series are suitable for high speed and high sensitivity applications. The spectral range extends from 350 to 1100 nm, … WebAug 22, 2024 · Bi2Te3 − xSex photoconductive detectors are attractive due to their linear photo-response (LPR), potential in ultrabroadband photo-detection, and compatibility with CMOS technology. However, as a fundamental issue for photo-detectors, the weak-light photo-response of Bi2Te3 − xSex detectors was covered by the bolometric response, the …
WebThe photoconductive detector is the most simple of the detector devices, where a single layer thin film or bulk material may be used. Schottky or ohmic contacts are then deposited to complete the device, with an example device structure shown schematically in Figure 12. The current density in the photoconductor will be given by (3) (4) WebLead Sulfide (PbS) and Lead Selenide (PbSe) photoconductive detectors are widely used in detection of infrared radiation from 1000 to 4800 nm. Unlike standard photodiodes, which produce a current when exposed to light, the …
