A leak detection system and method are characterized by scanning a surface of a vacuum package, generating a contour signal corresponding with the contour of the scanned surface, and comparing the contour signal with a stored contour signal of a similar package which is known to be free of leaks. The system includes a sensor such as a scanning device which scans a surface of the package and generates the contour signal. A signal processor connected with the scanning device processes the signal to generate a profile of the package surface. This profile is compared with a stored profile corresponding to a normal configuration for the package surface. When the scanned profile deviates from the stored profile, a leak within the scanned package is indicated.
