INTERFERENCE PATTERNS IN A BIREFRINGMENT-FARADAY-ROTATORY PLATE SYSTEM

We have studied the interference pattern produced under normal inciden ce by a system of two plane-parallel plates in sequence, one birefring ent and one Faraday rotatory. The interference pattern of transmitted light consists of strong fringes at large phase intervals with a set o f weak fringes between them. The ratio of intensities of the strong an d the weak fringes is much larger than that of birefringent, optically active plates studied earlier and the system appears more suitable fo r interferometric applications.
