description In some embodiments, an apparatus includes a housing and an image sensor that is coupled to the housing. The apparatus also includes a non-imaging optical system coupled to the housing that can output light to a surface and produce a scattered light component and a specular reflected light component. The image sensor and the non-imaging optical system are collectively configured in such a manner that during operation, the image sensor receives from a surface (1) at least a portion of the scattered light component and not the specular reflected light component or (2) at least a portion of the scattered light component having a magnitude and at least a portion of the specular reflective light component having a magnitude less than the magnitude of the portion of the scattered light component.
