Claim 15:
16. An apparatus for producing structured light and flood illumination, the illumination apparatus comprising:
a microlens array including microlenses arranged at a pitch P in at least a first direction;
a first array of first light sources; and
a second array of second light sources, the first light sources configured to emit light at a wavelength L, wherein the first light sources are located at a distance D from the microlens array, wherein

P2=2LD/N, 

and N is an integer with N≥1, and
wherein the second light sources include emitters with lenses located thereon,
wherein the first light sources are emitters without lenses located thereon,
wherein the lenses provide the second light sources with a physical size greater than a physical size of the first light sources, such that the light sources of the second array have an etendue greater than an etendue of the light sources of the first array,
wherein the light sources of the first array produce structured light, and
wherein the light sources of the second array produce a continuous area of light.
