Thermal Beating Noise Calculator
Spectrum case:
Gaussian
Lorentzian
Time resolution of data acquisition system [s]:
Bandwidth of light source [Hz]:
Polarization (real number between -1 and 1; 1 or -1 for linearly polarized light, 0 for unpolarized light):
Notes:
White out to measurement bandwidth for (bandwidth of light source)*(time resolution of DAQ) >> 1
Follows spectral bandwidth for (bandwidth of light source)*(time resolution of DAQ) < 1
Mixed case for all other parameter combinations
