An illumination apparatus includes a periodic microlens array (MLA) including microlenses arranged with a first pitch d1 in a first direction. The illumination apparatus also includes a first set of first radiation-emitting elements arranged with a second pitch d2 being an integer multiple of the first pitch d1 and configured to generate, in cooperation with the MLA, a structured light pattern. The illumination apparatus also includes a second set of second radiation-emitting elements arranged with a third pitch d3 being a non-integer multiple of the first pitch d1 in at least the first direction and configured to generate, in cooperation with the MLA, a pattern of lines or a beam for flood illumination.

Illumination apparatus

An apparatus includes a spectrometer. A housing is attached to a substrate and defines an illumination channel and a receiving channel. The illumination channel includes an illumination source mounted on the substrate and operable to produce light in a particular part of the spectrum. A light pipe is disposed over the illumination source so as to direct light from the illumination source out of the illumination channel toward a target. The receiving channel includes a sensor chip mounted on the substrate. The sensor chip includes light sensitive elements, each of which is selectively sensitive to a respective region of the particular part of the spectrum. The sensor chip further includes an electronic control unit operable to analyze signals from the light sensitive elements.
