    • Optical apparatus includes a matrix of light sources arranged on a substrate with a predetermined, uniform spacing between the light sources. A beam homogenizer includes a first optical surface, including a first microlens array, which has a first pitch equal to the spacing between the light sources and which is aligned with the matrix so that a respective optical axis of each microlens in the array intercepts a corresponding light source in the matrix and transmits light emitted by the corresponding light source. A second optical surface, including a second microlens array, is positioned to receive and focus the light transmitted by the first microlens array and has a second pitch that is different from the first pitch.
    • 光学装置包括在光源之间以预定的均匀间隔布置在基板上的光源矩阵。 光束均化器包括第一光学表面,第一光学表面包括第一微透镜阵列,其具有等于光源之间的间隔的第一间距并且与阵列对准,使得阵列中的每个微透镜的相应光轴截取对应的 矩阵中的光源并透射由相应光源发射的光。 包括第二微透镜阵列的第二光学表面被定位成接收和聚焦由第一微透镜阵列传输的光,并具有不同于第一间距的第二间距。
