Abstract
In some embodiments, an apparatus includes a housing and an image sensor that is coupled to the housing and has a field of view. The apparatus also includes a non-imaging optical system coupled to the housing and disposed outside of the field of view of the image sensor. The non-imaging optical system can output diffuse light in a set of directions to a surface to produce scattered light. The image sensor and the non-imaging optical system are collectively configured such that during operation, the image sensor receives at least a portion of the scattered light.
