Optical measuring method and an optical measuring apparatus for determining the internal structure of an object

摘要

An optical measuring method and an optical measuring apparatus are capable of obtaining the true mean time delay of a light waveform within a short time for the purpose of obtaining information on the internal structure of an object. Calculations include a first mean time delay when the light path includes the object, a second mean time delay when the light path does not include the object, and a subtraction of the second mean time delay from the first mean time delay to obtain a true mean time delay.
