Abstract
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.

A power and energy (PE) meter for sensing electromagnetic (EM) radiation, comprising:
- a sensor head, comprising:
- a sensor which absorbs EM radiation that impinges on said sensor;
- and
- a heat sink with which said sensor is in thermal contact, said heat sink including a through-hole located behind said sensor which allows at least some of the EM radiation which is not absorbed by said sensor to pass through said heat sink without being absorbed.
A power and energy (PE) meter for sensing directed electromagnetic (EM) radiation, comprising:
- a sensor head, comprising:
- a sensor, comprising:
- an absorber which is heated by EM radiation that impinges on said absorber;
- and
- a temperature measurement device arranged to produce an output which varies with the temperature of said absorber;
- and
- a metal heat sink with which said sensor is in thermal contact, said heat sink including a through-hole located behind said heat sensor which allows at least some of the EM radiation which is not absorbed by said sensor to pass through said heat sink without being absorbed;
- a means of applying mechanical pressure which holds said sensor in thermal contact with said heat sink;
- and
- a capture head mounted behind and physically separate from said sensor head, said capture head comprising an absorbing surface which absorbs at least some of said EM radiation which is not absorbed by said sensor and which passes through said heat sink without being absorbed.
