The invention relates to a method for the determination of physical properties of flows or currents using at least one sensor head, wherein fluctuations of a parameter are detected by at least three sensor heads, said detected fluctuations of a parameter are converted into measuring signals. A time of flight between a first pair of sensor heads of said at least three sensor heads is determined from correlating said measuring signals created by the two measuring signals of said first pair of sens...

Apparatus for obtaining three-dimensional shape data of an object including a controller for controlling a light beam, a scanning system for scanning an object by the controlled light beam, and an image receiving system for receiving the light reflected from the object in a prescribed range. A memory stores data for correction of illumination irregularities corresponding to positions in the prescribed range that the light reflected from the object is received, and the controller refers to the st...

A measuring arrangement includes forming first and second pairs of light beams each having a low frequency light beam and a high frequency light beam. Both pairs of light beams generate beat signals of the same frequency. The low frequency light beam of either pair and the high frequency of the other pair pass through a predetermined optical path to cause phase changes in the same direction. Beat signals are generated by superposing the first and second beam pair to provide measurement informati...

A measuring arrangement for measuring clearance between a bearing internal part and a bearing external part of a bearing, in particular in an aircraft or spacecraft, is disclosed. The idea underlying the measuring arrangement is to adjust the bearing part relative to the bearing external part with an adjusting device and to measure the adjustment carried out with a measuring device. The advantage according to the measuring arrangement is that a much more accurate and repeatable measuring may be ...

Apparatus 10 for measuring the head of a horse 12 incorporates various components, such as cheek straps 14, each of which is movable (slidable) relative to another component in order to produce an overall desired fit of the apparatus 10, which is generally in the form of a bridle, to the head 12. Once the desired fit has been achieved, windows 16 and numerals 18 allow measurements to be taken, indicating the relative positions of the slidable components. These measurements may give direct measur...
