Determination of dominant radiation in polariscope by means of babinet compensator

Technique developed by the authors has been found to be particularly useful in a photoelastic system when the information regarding the component transfer functions of all the elements are not known or cannot be obtained with ease

A new technique has been developed for determining the dominant wavelength of a narrow band of electromagnetic radiation in the visible and near-infrared ranges transmitted through a polariscope. This technique is based on the application of a Babinet compensator, for which the spectral dependence of the refractive indices for both ordinary and extraordinary rays, that is, the spectral birefringence of crystalline quartz, is known or has been determined.
