Method and System for Device Identification

A method for identifying a device with a pattern recognition process comprising:

• directing a source signal from an energy source towards a surface of a device for reflection therefrom;
• aligning each of a plurality of sensors on a different axis of the device and detecting from each sensor an interference pattern from the surface of the device, each interference pattern comprising a plurality of points;
• and
• with a computer:
• calculating what is approximately the absolute intensity of at least one of the plurality of points of at least one of the interference patterns;
• comparing each of the interference patterns to interference patterns in a stored set of interference patterns;
• determining whether a match exists between any of the detected interference patterns and a stored interference pattern by assessing whether the calculated intensity of the at least one of the plurality of points is within a predetermined range of allowable absolute intensities and, if so, determining whether to identify the device based on the stored interference pattern.

A system for identifying a medical device comprising:

• an energy source configured to direct a source signal onto a device such that the source signal is reflected by the device;
• a sensor configured to capture an interference pattern of the reflected signal including a plurality of points;
• and
• a computer configured to store the captured interference pattern, to calculate what is approximately the absolute intensity of at least some of the plurality of points, associate each of the calculated intensities with an allowable range of intensities, and assign a unique identifier to the device.
