The Head

n

The head is a photo-acoustic detector using a closed air-cell and a pressure transducer.

nn

Calibration is provided by ohmic heating of a thin metal film within the cell.

n

The Support Unit

n

The support unit is based around a National Instruments USB-6211 data acquisition module.

nn

Additional electronics have been added to provide film heating for calibration and to amplify

nn

the signal from the head's microphone pressure sensor. The compiled software, written in

nn

LabVIEW, implements a lock-in amplifier and displays the microwave power.
