摘要： The proposal is for a device for absolute two-dimensional position measurement of a part (10) in relation to a measuring arrangement (11) in which the surface of the part (10) is in the form of a hologram. The information in the hologram is read off with a measuring wave (13) aimed at and diffracted from the hologram (18) by interference with a reference wave (14). The interfering waves (13, 14) are detected by an optical sensor arrangement (20) containing at least two sensors (21, 22). The absolute position is found in a signal processing arrangement either from the radiation intensities detected by the sensors (21, 22) or from the phase relationship between the signals emitted by the sensors (21, 22) by comparison with a stored value.

摘要： The laser diode (1) of the laser vibrometer described emits light which is directed by a lens (2) on to a polarizing beam splitter (3). Part of the beam passes straight through to an imaging lens (4) and the other part is deflected on to a mirror (5). Located between the beam splitter and the lens and between the beam splitter and the mirror are quarter-wave plates (6 and 7). The whole of the beam reflected by the mirror passes through the beam splitter on to a photodetector unit (8). The beam deflected by the test object (9) vibrating in direction (14) is also deflected on to the same photodector unit. The output signal of the photodector unit, i.e. the interference signal produced by the superimposition of the two reflected beams, is fed to an electronic evaluation unit (10). Also fed to the processing unit is a signal from a current modulator (11) which, in addition, supplies the laser diode with modulated injection current through line (12). The distance between the imaging lens and the test object forms an additional optical path (13) which is significantly longer than the reference path.

摘要： A device for interferometric measurement of surface structures by measurement of the phase difference in laser speckle pairs in the measurement points on this surface comprises at least two laser sources (10-12) whose frequency or wavelength is modulated, a beam splitter (16) which splits each laser beam produced into two partial beams, means for shifting the frequency of the two partial beams relative to each other and a beam-guide device by means of which one of the partial beams as a reference beam and the other as a measurement beam, which is directed to and reflected from the measurement point, are interferometrically superimposed and directed to a photoreceptor device (25) connected to an evaluation device (27) for determining the phase difference. The beam splitter is connected on the input side via an optical fibre line (13-15) with the at least two laser sources (10-12) and the two partial beams emerging from the beam splitter (16) likewise travel, at least for a partial section, in optical fibre lines (17 and 18). One of these fibre lines (17) has an extension (19) in relation to the other. In this way, a measurement beam and a reference beam with slightly differing frequencies can be produced simply and economically, with a compact structure and minimal adjustment.

摘要： The present invention relates to a method for measuring the positions and the position changes, as well as the physical quantities derivated therefrom, of an element to be examined according to the method of heterodyne interferometry. In order to generate the heterodyne frequency, a laser is modulated by means of a time-varying injection current in such a way that its radiation frequency is changed, that the radiation is directed toward the element to be examined by using an optical deviation on one side and no optical deviation on the other side, and then redirected to a measuring receiver. With regard to a small-sized object, the measured values are better assessed if the shape of the injection current signal is characterized by a steep rising edge in relation to its pulse duration, followed by a plateau.

摘要： The proposal is for an optical sensor for rotary movements comprising a semiconductor laser (10) which is switched on at least at intervals and the frequency-modulated radiation (11, 50) of which is divided into two partial beams (13, 14; 51, 52) which pass trhough an annular optical fibre arrangement (17) in opposite directions, are then superimposed as outcoupled signals (13''', 14'''; 51'''', 52'''') and taken to a photodetector (21) which provides an output signal (26, 58) having a predeterminable heterodyne frequency and the phase relation of which in relation to a reference signal makes it possible to find the rotation rate of the arrangement (17). The sensor of the invention can be fitted in integrated optics and all the optical radiation can be conducted in optical fibres. The sensor of the invention is especially suitable as a fibre gyro or rotation rate sensor.

摘要： A method is proposed for the optronic measurement of path lengths and angles. A first and a second optical beam (13, 14 or 61, 63) are directed, at given angles (a and b), at the surface (12) of the object to be measured so that both beams impinge on the surface at the same point, where diffraction will occur. In one embodiment of the invention, the two beams (13, 14 or 61, 63) have different frequencies. In another embodiment, the frequency of each beam is changed simultaneously and one of the beams is phase-modulated. The phase change in the output signal from the sensor (18) is determined by comparison with a reference signal.
