PHOTOSENSITIVE DIAGNOSTIC DEVICE

摘要

The present invention relates to a photosensitive diagnostic device configured to project an optical signal, capture reflected portions of the optical signal, and convert the captured portions of the optical signal into an electrical signal indicative of characteristics of a sample analyzed by the device. In accordance with one embodiment, a photosensitive diagnostic device comprises an illumination source and a detector. The illumination source comprises an output face configured to project an optical signal characterized by at least one diagnostic frequency. The detector comprises a photosensitive input face configured to capture reflected portions of the optical signal. The photosensitive input face of the detector is further configured to convert the captured portions of the optical signal into one or more electrical signals at least partially representing a degree of change in the diagnostic frequency of the optical signal. The output face of the illumination source and the photosensitive input face of the detector lie in a substantially common plane. The present invention further relates to a diagnostic system comprising an embodiment of the photosensitive diagnostic device herein described.
