Abstract
Apparatus for measuring spectral reflectance of a surface, the apparatus comprising: a chamber comprising a wall formed having an aperture defined by an aperture boundary; a light source mounted to the chamber and having a field of illumination (FOI) configured to intersect the aperture at an illumination intersection; and an optical fiber mounted to the chamber and having a field of view (FOV) configured to intersect the aperture at an imaging intersection; wherein the chamber is configured so that when the aperture is positioned on a surface the chamber substantially prevents light from entering a volume of the chamber.
Claims19
An apparatus for measuring spectral reflectance of a surface, the apparatus comprising:
- a chamber comprising a wall formed having an aperture defined by an aperture boundary;
- a light source mounted to the chamber and having a field of illumination (FOI) configured to intersect the aperture at an illumination intersection, and controllable to illuminate the aperture from different poses, each pose defined by a position of the light source and an illumination direction along which the light source illuminates the aperture;
- and
- an optical fiber mounted to the chamber and having a field of view (FOV) configured to intersect the aperture at an imaging intersection;
- wherein the chamber is configured so that when the aperture is positioned on a surface, the chamber substantially prevents light from outside the chamber from entering a volume of the chamber.
