Paper Abstract

Real time measurement will be reported on the time variations of both the refractive index and geometry of transparent samples. The temperatures of the samples were varied while they were in a parallelism interferometer and the two independent sets of fringe patterns were monitored. One pattern gave the geometric variation, while the others gave the optical path profile. Resolution of quarter wave are readily realized.
