Two-beam spectroscopy optical setup alternatives
What is it about?
Two-beam spectroscopy uses two beams of light that propagate at a certain angle and form an interference pattern, which can be used to determine the wavelength of the light. The same two beams are generated in the so-called heterodyne spectroscopy but differ in the sensitivity of the measurements, and on the range of the spectroscopic measurements. But how are compared the two methods sensitivities ? this paper suggests that under some premises similar sensitivities to the heterodyne spectroscopy can be potentially achieved.
Why is it important?
Our findings points out that spectroscopic ranges can be broadened with potentially the same resolution of heterodyne spectroscopy.
