Apparatus for delay-sensitive measurement of a signal

摘要

The method involves mixing the instant values of partly intensity-modulated signal and a reference signal. The mixed signal value is further combined with the detected instant values of reference signals having frequencies to obtain respective measurement signal values. The amplitude and/or phase position of a partly intensity modulated signal is calculated from two measurement signal values. Independent claims are also included for the following: (A) a device for calculating the amplitude and/or phase position of a partly intensity modulated signal (B) a 3D camera with a mapping lens system.
