Abstract
A patterned line of optical radiation can be steered in the other two directions (e.g., line patterned in y, steered in x and z) with a 1-D phase shifter array in a Fourier optics configuration. Preferably the patterned line is provided by forming a line focus and modulating it with an array of grating light valve devices in an amplitude modulation configuration. Phase modulation is preferably provided with an array of grating light valve devices in a phase modulation configuration.
