1. A system for detecting a direction of a source of a laser beam, comprising:

  • (a) a pixelated sensor that is sensitive to the laser beam;

    (b) a mask, disposed between the source of a laser beam and the pixelated sensor, the mask including an opaque portion that is opaque to the laser beam and a window portion that is at least translucent to the laser beam so that when the laser impinges upon the mask an image of the window portion is projected onto the pixelated sensor; and

    (c) a processor that determines an angle of incidence of the laser beam with respect to the mask by determining a number of pixels that the image of the window is offset from where the image of the window would be if the laser beam had been normal to the mask.
