    4. TECHNICAL INFORMATION “Measurement principles” This instrument adopts the Fourier domain method that splits the light from the light source and directs that light toward the reference mirror (reference light) and toward the patient’s eye (measurement light) using the interferometer at the head of the measurement unit, and then matches the reflected light and detects interference signals of each waveform (spectrum interference signal).
