Abstract
Glassware inspection apparatus comprises a first light emitting diode position to illuminate a first region of the ware, a first driver for driving the first light emitting diode in a first modulated mode, a first photodetector positioned for receiving light of the first light emitting diode which illuminates the first region of the container, and a first demodulator for the output of the first photodetector. The apparatus also comprises a second light emitting diode positioned to illuminate a second region of the container, a driver for driving the second light emitting diode in a second modulated mode, a second photodetector positioned for receiving light of the second light emitting diode which illuminates the second region of the container, and a second demodulator for the output of the second photodetector. The two modulation modes minimize cross-talk between the first and second light emitting diodes.
