Abstract: A time-of-flight (ToF) module includes a light source, a driver module, and a light sensor. The driver module includes electrical circuitry configured to selectively drive the light source to emit pulsed illumination light. The light sensor is configured to sense returning light reflected from a target. At least one of the light source, driver module, and light sensor is stacked on another to reduce a footprint of the ToF module.

Abstract: A projector for illuminating a target area is presented. The projector includes an array of emitters having a plurality of subarrays and an optical assembly. Each subarray includes one or more independently addressable channels emitting light in accordance with emission instructions. At least two of the subarrays are adjacent to each other and do not overlap. The optical assembly is configured to tile portions of the emitted light to form a light pattern for projection to a target area. The light pattern has a first plurality of sections and a second plurality of sections. Each section of the first plurality represents a first respective portion of the light pattern emitted from a corresponding subarray. Each section of the second plurality represents a second respective portion of the light pattern formed by tiling light emitted from two or more of the subarrays.
