Claim 1
Independent Claim
180 words
THE METHOD OF OPTICAL SPECTRUM ANALYSIS WITH AN INTERFEROMETER HAVING A RECIPROCABLE MIRROR AND HAVING PHOTOELECTRIC DETECTING MEANS IN ITS LIGHT EXIT PATH, COMPRISING THE STEPS: DIRECTING LIGHT WITHIN AN APPRECIABLE SPECTRAL RANGE OF OPTICAL FREQUENCIES FROM A SOURCE TO BE EXAMINED THROUGH THE INTERFEROMETER; RECIPROCATING THE MIRROR WITH SUBSTANTIALLY CONSTANT VELOCITY OVER AN APPRECIABLE PORTION OF EACH RECIPROCATING CYCLE, AT AN EXCURSION, AND AT A REPETITION RATE TO PRODUCE FLUCTUATING LIGHT AMPLITUDE OUTPUTS AT FREQUENCIES RELATED TO THE COMPONENT OPTICAL FREQUENCIES CONTAINED IN THE SOURCE OF LIGHT TO BE EXAMINED; DIRECTING AND FLUCTUATING LIGHT AMPLITUDE OUTPUTS ON TO SAID PHOTOELECTRIC DETECTING MEANS; AND ANALYZING THE AMPLITUDE OF EACH FREQUENCY COMPONENT OF THE OUTPUT SIGNAL OBTAINED FROM SAID PHOTOELECTRIC DETECTING MEANS DURING THAT PORTION OF EACH RECIPROCATING CYCLE DURING WHICH THE VELOCITY OF THE MIRROR IS SUBSTANTIALLY CONSTANT TO PROVIDE AN INDICATION OF THE INTENSITIES OF THE VARIOUS FREQUENCY COMPONENTS WITHIN THE SPECTRAL RANGE OF SAID SOURCE, AND INDICATING THE DISTRIBUTION OF THE OPTICAL ENERGY OF SAID LIGHT SOURCE AMONG THE VARIOUS CORRESPONDING WAVELENGHTS CORRESPONDING TO THE VARIOUS FREQUENCY COMPONENTS.
