A dot array illuminator includes an illumination source that includes one or more source arrays and a microlens array (MLA). A source array is an array of light emitting components. The source arrays are positioned on a substrate according to a geometric configuration. The MLA includes lens arrays that are arranged in a similar geometric configuration. The microlens array are separated from the source arrays by a distance and are substantially parallel to the source arrays. The microlens array overlaps with the source arrays and is of a dimension such that it can receive substantially all light emitted by the illumination source. The illumination source emits light towards the MLA. The MLA receives the light and outputs structured pattern light by interpolating received light.
