Cavity Spacing Glitch Spectrometry

We have recently reported an interesting new approach to quantitative spectro-metric measurement. As the Mark I semiconfocal Fabry-Perot cavity (Section 5.3) was tracked in sjmchronism with the MMW source through a sample 

The cause of the glitch proved to be inherent in the performance of the servo system when locking to a cavity profile whose Q was reduced by a narrower
