摘要： The invention relates to an optical-electronic distance measuring method according to the phase measurement principle by emitting of optical measuring radiation, which is modulated according to the burst modulation principle, having a burst period duration made of an active burst time and a dead time, receiving at least a part of the measuring radiation (23), which is reflected on the measured object, wherein transforming into an input measuring signal (ES) is performed, and determining a distance to the measured object by analyzing a measuring signal (MS, gMS) generated from the input measuring signal (ES).

摘要： The invention concerns a device for calibrating distance-measuring apparatus. A transmitter (1) emits high-frequency modulated optical radiation which is reflected by an object to be measured and is received by a measurement receiver (2). Part of the transmitter radiation is always decoupled as reference radiation and guided via a calibration path to a reference receiver (3) whose electrical signals are fed to a frequency mixer (4). The frequency mixer (4) and the avalanche photodiodes acting as measurement receivers (2) of the measuring radiation are interconnected directly via an electrical connection line (5) upon which a mixer frequency acts. As a result thereof, optoelectronic calibration which completely compensates the temperature-dependent phase shifts of the avalanche photodiodes is possible. Since, in addition, the phase shifts generated in the reference and receiver signals by the temperature drifts of the transmitter (1) compensate one another, the overall accuracy of the distance measurement is increased, in particular for short measuring times and immediately after the apparatus has been switched on. Furthermore, in comparison with a successive mechanical calibration process, the measuring times are halved and advantages in terms of weight, cost and reliability are afforded since a mechanical change-over device is dispensed with.

摘要： The invention relates to an electro-optical distance-measuring device, more particularly a laser rangefinder, with a transmitting unit for transmitting intensity-modulated optical radiation, a receiving unit for receiving a portion of the optical radiation reflected back from a target in a photosensitive electrical component and converting it into an electrical received signal, an input filter for filtering the received signal, an analogue-to-digital converter for digitising the filtered received signal and an electronic analysis unit that calculates the distance from the rangefinder to the target object on the basis of a signal propagation time using the digitised received signal. The input filter is implemented as a time-discrete and continuous-value filter structure, more particularly a digital filter structure.

摘要： The invention relates to an optical inclinometer, in which radiation (S) is emitted from a radiation source (2). After passing through a receptacle (6, 6') containing at least one first medium (11, 13), said radiation (S) is reproduced in a camera (9). Information concerning the inclination of the inclinometer can be gathered from the position of the first medium (11, 13), in particular a liquid level, in relation to the inclinometer or the camera (9). The recording of the position of the first medium (11, 13) by a camera (9) permits the evaluation of a plurality of characteristics, in particular the form, dimension and position of a boundary layer (14).
