Abstract: A scanner that reads optical luminance at a field of view (FoV) includes an illuminator that provides light beams to a surface that may be located from a near field to a far field of the FoV. The illuminator can provide optical luminance that has an irradiance, which is uniform or within a certain range from the near field FoV to the far field FoV. The irradiance is achieved by adjusting the location of light emitting components and adjusting the power.

Abstract: A time of flight sensor system having a time of flight sensor layer is disclosed. The system includes a covering window layer spaced apart from the time of flight sensor layer, with an exit window and an entrance window, an emitting element in the time of flight sensor layer that transmits an emission signal, a receiving element in the time of flight sensor layer that receives a reception signal, one or more opaque walls, and light baffles incorporated into the one or more opaque walls. The one or more opaque walls extend at least a portion of the distance from the time of flight sensor layer to the covering window layer. The one or more opaque walls reduce the reflection backscatter of emission signals and reception signals. The light baffles in the one or more opaque walls reduce backscatter of emission signals and reception signals.
