ABSTRACT:
A plurality of fiber optic laser members are supported in an apertured plate so as to form an array supplied by an optical pump. Individual members may have the light passing there through modulated by respective modulators. Light from the fiber optic laser array illuminates an optical storage medium which stores information. The resulting output undergoes Fourier transformation and optical filtering. Filtered light then undergoes inverse Fourier transformation and detection.
