In this paper, we present a perturbation method for solving a second order difference equation with variable coefficients with some additional assumptions.
An analog system capable of retrieving the phase information from an interference pattern in real-time is described and some experimental results presented.
It is often useful to know the effect an optical component has on the phase of light passing through it.
By O. P. CLARK, E. J. DRAZY, and D. C. WELLER The carriers and pilot tones of the L multiplex are all derived from a single source of 4 kc.
A number of methods 1-4 have been suggested for realizing optical switches in integrated optical format; in many cases, the schemes are extensions of the microwave art.
We describe a phenomenological approach to polarization dispersion in long single mode fibers that is based on the existence of principal states of polarization.
We argue that subroutine libraries are not enough but need to be supplemented by common file formats and directly executable commands.

In analyzing the performance of an acoustic or microwave radiator'it is helpful to know the way in which the waves proceed as they emerge from the source.
