POWER AND ENERGY METER FOR MEASURING ELECTROMAGNETIC RADIATION

摘要

A power and energy (PE) meter includes a sensor head comprising a sensor which absorbs EM radiation that impinges on it, and a heat sink with which the sensor is in thermal contact. The heat sink includes a through-hole behind the sensor which allows at least some of the EM radiation which is not absorbed by the sensor to pass through the heat sink without being absorbed. A means of applying mechanical pressure is preferably employed to hold the sensor in thermal contact with the heat sink. A capture head and shroud may be mounted behind and physically separate from the sensor head, and arranged to absorb at least some of the radiation which is not absorbed by the sensor head.
