摘要：

Theoretical limitations of optical heterodyne detection with pyroelectric detectors are discussed. It is shown that the minimum detectable power P m of Sr1-xBaxNb2O6 pyroelectric detectors at 10.6μ, with an intermediate frequency of 1 MHz and a local oscillator power PL = 1 W is Pm = 8×10 -16 W/Hz. An experimental heterodyne receiver with the above conditions is shown to have a value Pm = 1.5×10-11 W/Hz where amplifier noise is much larger than detector noise. The theoretical and experimental dependence of Pm on PL are compared in the amplifier noise limit. © 1969 The American Institute of Physics.
