Abstract
A method for detecting a coating on a bottle includes directing light at a first point of incidence on the bottle and detecting a first intensity of reflected light from the first point of incidence on the bottle. Further, light is directed at a second point of incidence on the bottle and a second intensity of reflected light from the second point of incidence on the bottle is detected. The first intensity is compared to the second intensity to determine whether the coating on the bottle has been uniformly deposited.

A detection system comprising:
- a probe shaft comprising:
- a cylindrical sidewall comprising:
- an interior cylindrical surface;
- and
- an exterior cylindrical surface;
- and
- a light transmitting guide aperture extending between the interior cylindrical surface and the exterior cylindrical surface at a non-perpendicular angle with respect to a longitudinal axis of the probe shaft;

- a light detector for receiving reflected light from the point of incidence on the substrate, the detection system for detecting a coating on the substrate;
- and
- a light transmitting guide coupled to the light source, wherein a tip of the light transmitting guide is mounted within the light transmitting guide aperture at the angle, a light emitting face of the light transmitting guide protruding from the exterior cylindrical surface.
A detection system for detecting a coating on a substrate comprising:
- a detection probe for directing light at a point of incidence on the substrate and for receiving reflected light from the point of incidence on the substrate, the detection probe comprising:
