ABSTRACT:
Optical measuring apparatus including an acousto-optical device (3) which molulates either the angle or the wavelength of a light beam (1) at a frequency determined by a signal generator (15). A detector (13) detects the modulated beam after interrogation of a sample under test; and a lock-in amplifier (14) is connected to the signal generator (15) and to the detector (13) to determine the differential of an optical property of the sample under test.
