Classification: CPC B  G | IPC B  G

Claim 12:
13. The method of claim 12, wherein:
emitting light energy comprises:
emitting light energy, by a first light source, at the first, absorption wavelength at the portion of the transparent hollow article as the transparent hollow article moves along the travel path past the first light source; and
emitting light energy, by a second light source, at the second, reference wavelength at the portion of the transparent hollow article as the transparent hollow article moves along the travel path past the first light source;

the method further comprises the step of sequentially operating the first and second light sources;
sensing the light energy comprises sensing by a single light energy sensor; and
the processor is in communication with the single light energy sensor; and

computing the wall thickness comprises computing, by the processor, the wall thickness of the portion of the transparent hollow article based on the intensity of light energy sensed by the single light energy sensor.
