Abstract
The invention is a method and apparatus for the refraction of an optical ray from a first focal point to at least one other focal point. The method includes the steps of passing the optical ray through an optical medium to establish a first focal point and then launching acoustic waves into the optical medium to induce at least one half standing acoustic wave within the optical medium. The induced refractive index gradient deviates the optical ray from the first focal point to at least one other focal point. This method of induced refraction can be utilized as a chopper in one embodiment and as a high energy dissipation means in an alternative embodiment.
