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 display screen that includes OLED pixels disposed at a particular pitch in a first plane. A light projector includes light emitting elements disposed in a second plane parallel to the first plane. The light emitting elements are disposed at the same pitch as the OLED pixels or at an integer multiple of the pitch of the plurality of OLED pixels. The light emitting elements are operable to produce light at a wavelength for transmission through the display screen, and the first and second planes are separated from one another by a distance D such that d=2*(λ)*(D)/(N), where d is the pitch of the OLED pixels, λ is the wavelength, and N is a positive integer.
