Abstract:
A system is provided for measuring gloss and spatial dependence of gloss. In a first embodiment, the system comprises: a first illuminator configured to emit a first light beam at a point on a target, thereby producing a generally specular reflectance in a first direction; a second illuminator configured to emit a second light beam at the point on the target, thereby producing generally diffuse reflectance in the first direction; a linear array sensor configured to detect the generally specular reflectance and the generally diffuse reflectance in the first direction; and a processor configured to process the generally specular reflectance and the generally diffuse reflectance detected by the linear array sensor. In a second embodiment, the system comprises: an illuminator configured to emit a beam of light at a point on a target, thereby producing a generally specular reflectance in a first direction and generally diffuse reflectance in a second direction; a first linear array sensor configured to detect the generally specular reflectance in the first direction; a second linear array sensor configured to detect the generally diffuse reflectance in the second direction; and a processor configured to process the generally specular reflectance detected by the first linear array sensor and the generally diffuse reflectance detected by the second linear array sensor.
