ABSTRACT

A leak detection system includes an emitter, detector, and electronic control
unit (ECU). The emitter directs electromagnetic energy having a predetermined
wavelength range, e.g., infrared energy, toward a surface of a product. The
product defines an enclosure chamber containing a trace gas. The detector is
positioned between the emitter and the product at an offset distance from the
surface. The detector detects reflected energy. The ECU receives a signal from
the detector that is indicative of a spectrum of the reflected energy and
identifies a detected leak in the product. This includes comparing the
spectrum of the reflected energy to a predetermined spectrum of the trace gas.
The trace gas has a wavelength within the predetermined wavelength range of
the emitter. The ECU generates an output signal in response to the leak, with
the output signal identifying a presence and location of the leak.
