A beam of light reflected from the mirror would trace patterns which depended on the frequencies of the sounds. One of the best examples can be found in the opening sequence of the outer limits tv series. Lissajous figures are obtained for the interference of two perpendicular oscillatory motions of different frequencies. The analytical expression for the propagation of lissajous singularities through an astigmatic lens is derived and used to study the dynamic evolution of lissajous singularities after passing. If the frequency and phase angle of the two curves are identical, the resultant is a straight line lying at 45 and 225 to the coordinate axes.
