Determining the amplitude-frequency characteristics of the thermoanemometer + sensor system by laser pulse

An experimental method is proposed for determining the frequency response of a hot-wire and hot-film system using short-pulse laser action on a sensor. The possibility to obtain frequency response by this method is demonstrated. The frequency response is obtained from constant temperature anemometer...

Zusammenfassung:An experimental method is proposed for determining the frequency response of a hot-wire and hot-film system using short-pulse laser action on a sensor. The possibility to obtain frequency response by this method is demonstrated. The frequency response is obtained from constant temperature anemometers of two manufacturers with two types of sensors: surface thin-film and wire.
