Abstract :
The observation and quantitative measurement of optical heterodyne detection in the far infrared (IR) (λ=118.6 μm) using a Ge:Ga detector are reported. The experimental results fall below theoretical predictions; the discrepancy is explained in terms of the NEP of the detector used and the low value of local oscillator power available in the experiments.
