Abstract

An optical instrument assembly includes a transmitter (12) for emitting an optical signal onto a specimen, a detector (40) for detecting a light emitted from the specimen, a first drive mechanism (50) for varying the position of the signal onto the specimen, and a locator (100) for determining the location of the first drive mechanism relative to the specimen.
