Photosensitive diagnostic device

A photosensitive diagnostic device comprising an illumination source and a detector, wherein:

• 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 at 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;
• and
• the output face of the illumination source and the photosensitive input face of the detector are exposed such that the output face and the photosensitive input face are configured to contact a surface of the sample to be analyzed by the device.
