Pyrite detectors can be as sensitive as a modern 1N34A germanium diode detector. Lead sulfide is a semiconductor, a photoconductor, and an extremely sensitive infrared radiation detector. Detector and power rectifiers could not amplify a signal. The brightness of the signal depends on the number of secondary electrons reaching the detector. Precision of time measurement with a scintillation detector is proportional to . Events are detected by measuring deformation of the detector sphere. OceanEye aft radar and a magnetic anomaly detector (MAD). Sonobuoy Receivers, and the ASQ-81 Magnetic Anomaly Detector. Some GC-MS are connected to an NMR spectrometer which acts as a backup detector. Marconi used this device as a radio detector. "Synthetic array lidar" allows imaging lidar without the need for an array detector. Bor-1 magnetic anomaly detector (MAD) and other operational equipment. Radiation that is scattered towards the detector is counted. The popularity of gas chromatography quickly rose after the development of the flame ionization detector. They are based on the micropower impulse radar stud detector invented by Thomas McEwan.
