The invention provides an improved illumination system for use in imaging systems that may produce a non-overlapped near field image in the slow axis direction, and a far field image of the illumination source in the slow axis direction at a light modulator. In an embodiment, the illumination system produces an area of illumination for a light modulator along a slow axis direction and along a fast axis direction, and includes a plurality of laser diode emitters, a first array of first micro lenses, and a second array of second micro lenses. The plurality of laser diode emitters are arranged in an array, and each of the laser diode emitters produces illumination in a slow axis direction and in a fast axis direction. Each first micro lens in the first array corresponds to one of the laser diode emitters, and collimates illumination in the slow axis direction. Each of the second micro lenses of the second array corresponds to one of the first micro lenses. Each of the second micro lenses is arranged to receive illumination from one of the first micro lenses. The first micro lenses produce a non-overlapped near field image in the slow axis direction.
