Multipurpose optical sensor

An optical sensor, comprising:

• a cable with a leading end;
• and
• an optical system disposed at said leading end of said cable, said optical system including:
• a plurality of optical fiber pairs disposed within said cable and concentrically extending from said leading end of said cable, a first optical fiber of a first pair of said plurality of optical fiber pairs being positioned opposite a second optical fiber of the first pair;
• a first optical device disposed at an end of the first optical fiber to direct a light beam emanating from the first optical fiber perpendicularly across an axis of said cable;
• and
• a second optical device disposed at an end of the second optical fiber to receive the light beam directed from the first optical fiber and to transfer the light beam into the second optical fiber,
• wherein the first pair of said plurality of optical fiber pairs measures a first type of measurement and a second pair of said plurality of optical fiber pairs measures a second type of measurement different from the first type of measurement.
