Abstract
A shared optic assembly for combined flood and dot illumination modules is disclosed. The shared optic assembly includes a first high-powered VCSEL element for providing a flood beam and a second high-powered VCSEL element for providing a dot beam, where both the first and second VCSEL elements share the same optics and are incorporated onto the same module for space savings.
Claims16
A vertical-cavity surface-emitting laser (VCSEL) illuminator assembly comprising:
- a first VCSEL array configured to generate a dot beam;
- a second VCSEL array adjacent to the first VCSEL array, the second VCSEL array being configured to generate a flood beam;
- and
- diffuser optics shared by the first VCSEL array and the second VCSEL array, wherein
- the diffuser optics are configured to receive the dot beam and the flood beam respectively emitted from the first VCSEL array and the second VCSEL array,
- the diffuser optics comprise an outer face that faces the first VCSEL array and the second VCSEL array, and
- the first VCSEL array and the second VCSEL array are each configured to respectively direct a portion of the dot beam and a portion of the flood beam at a common location on the outer face of the diffuser optics.
