ABSTRACT:
Increasing signal to noise ratio in optical spectra obtained by spectrophotometers. An interferometer introduces interference effects into a source light beam. A dual beam configuration splits the source beam having the interference effects into a reference beam and a sample beam. The reference beam interacts with a reference substance and is detected by a reference detector. The sample beam interacts with a sample substance and is detected by a sample detector. An optical spectra of the sample is based on the difference between the detected reference beam and the detected sample beam.
