    Abstract: An optical measurement method includes: preparing an optical system for recording a hologram caused by modulating, with a reference beam, an object beam obtained by illumination of a sample with illumination light, the reference beam being coherent to the illumination light; arranging a calibration unit on an optical path of the illumination light in a state where there is no sample, the calibration unit including an optical system that produces a known optical wave distribution; recording a first hologram caused while the calibration unit is producing an optical wave distribution; and calculating information about an optical wave distribution of the reference beam based on information indicating a position where the calibration unit is arranged, the known optical wave distribution, and the first hologram.

    Abstract: Coherent spectroscopic methods are described, to measure the total phase difference during an extended interrogation interval between the signal delivered by a local oscillator (10) and that given by a quantum system (QS). According to one or more embodiments, the method may comprise reading out at the end of successive interrogation sub-intervals (T i ) intermediate error signals corresponding to the approximate phase difference (Õ) between the phase of the LO signal and that of the quantum system, using coherence preserving measurements; shifting at the end of each interrogation sub-intervals (T i ) the phase of the local oscillator signal, by a known correction value (Õ (i) FB ) so as to avoid that the phase difference approaches the limit of the inversion region; reading out a final phase difference (Õ f ) between the phase of the prestabilized oscillator signal and that of the quantum system using a precise measurement with no restriction on the destruction; reconstructing a total phase difference over the extended interrogation interval, as the sum of the final phase difference (Õ f ) and the opposite of all the applied phase corrections - ˆ‘ i Æ FB i .
