    摘要: According to the invention a reference measurement is carried out without or with only one measurement object and the frequencies of the noise fraction are determined for the resulting frequency spectrum. Discrete measurement values are determined at equidistant sampling points in the form of complex-value overlays of oscillation functions and the noise and useful frequencies and by means of mathematical calculation methods corrected by the noise fractions. The measurement values corrected in this way are then subjected to a known method of frequency analysis.

    摘要: The invention relates to arrangements and methods for improving the signal and transmission properties of laser/electro-optical mixers (EOM) of measuring and data transmission links. The idea of attempting to suppress coherent properties of laser light is novel since, until now, the aim has always been to obtain the greatest possible coherence or coherence length in most technical applications. The invention has the following features: suppressing coherence and intensity fluctuations in the beam path of laser EOM by using optical methods and suppressing the coherence in the output radiation of the laser source, e.g. by a remodulated current pulse modulation or excitation of a number of modes within a laser diode (VCSEL).

    摘要: An imaging method is provided for imaging or locating an object with a wave-based sensor. A wave field emanates from the object as an object signal, with this object signal emanating from a sensor is received at a sensor position, and wherein the sensor(s) and the object assume a number of spatial positions with respect to each other and form a synthetic aperture, and an echo signal is sensed at each of these sensor positions, a number of function values is extracted from the echo signals, which are allocated to a space coordinate of the object, and a signal with a residual phase characteristic is formed from the function values. Based on a residual phase characteristic that is due to a deviation of real sensor positions from assumed or measured sensor positions, an image point, the object position or the relative movement of the object is determined.
