Abstract

A system includes a source, a detector, and a controller. The source is configured to emit electromagnetic energy toward two plies of film. A portion of the emitted electromagnetic energy is within a range of wavelengths. The detector is arranged to detect electromagnetic energy propagating away from the two plies of film. The detector detects electromagnetic energy within the range of wavelengths and generates signals indicative of intensity of detected electromagnetic energy. The controller controls operation of the foam-in-bag system based the signals from the detector. The film is transmissive of electromagnetic energy in the range of wavelengths. When dispensed between the two plies of film, one or both of foaming chemical precursors or foam formed from a reaction thereof is opaque to electromagnetic energy in the range of wavelengths.
