WebAn optical detector is required to have 15 dB signal to noise power ratio. The noise equivalent power (NEP) is background limited. (a) Calculate the power ratio P s /P n. Given that the response of the detector is limited by the background noise, what is the minimum detectable power expressed in terms of the NEP. (b) Web1 day ago · A gas detector measures and indicates the concentration of certain gases in the air via different technologies. Typically employed to prevent toxic exposure and fire, gas detectors are often battery-operated devices used for safety purposes. They are manufactured as portable or stationary (fixed) units and work by signifying high levels of … WebCan be more complicated to align detector pairs. Sensitive to ambient light and requires careful shielding. Photo Transistors and IR Detector Pairs A more current and popular optical detection solution these days is the IR Detector pair. This circuit makes use of a matched Infrared Transmitter and Receiver spanning the track to detect occupancy. on time chinese
