Abstract

A method for detecting a non-fixed object in a system (12) is provided. The method includes applying a light emitting substance (13) to at least a portion (14) of an object (10). At least a section (20) of the portion (14) is illuminated with a non-fixed object illuminator (16). The object (10) is detected in the system (12) in response to illuminating the section (20). The object (10) is then determined to be a fixed or non-fixed object.
