MEASURING SYSTEMS

UDC 681.586.5

The temperature-measurement error that arises in using 
a phase sensor based on the homodyne Mach-Zehnder interferometer 
has been estimated. Criteria for choosing the radiation wavelength 
and the stabilization accuracy of the injection-laser radiation power 
with allowance for the temperature dependence of the spectral sensitivity 
of semiconductor photodetectors have been obtained.
