Apparatus, and associated method, for detecting contamination of an object

摘要

An apparatus (36), and an associated method, for a portable electronic device, such as a wireless device, to determine luminescence of an object of interest (38). Ultraviolet A (UVA), or other appropriate, light energy is caused to be generated at a flicker rate. Images of the object of interest are recorded both when the UVA light energy is incident on the object of interest and in the absence of incidence of the UVA light energy on the object of interest. The images are compared, and a determination is made of the luminescence of the object of interest.
