Zespółdr Eng. Gregory WieczorekIstota wynalazkuZnanych are many methods of remote distance measurement. The idea of ​​the vast majority of work rangefinders boils down essentially to measure the time of flight of light to the measured object and back to the device, so that the main problem is a very precise measurement of time. Achieving millimeter resolution distance measurement requires time interval measurement with the precision of the order of some picoseconds (a billionth of a second). In the case of laser rangefinders can distinguish two main groups of methods of measuring the distance (based on the measurement time). The first group may include those that use the measurement of phase shift signal (typically sinusoidal) modulates the light output of the laser, while in the second group are methods in which the measurement of the time of flight of the light pulse.

Rangefinders, the operation of which is based on the measurement phase, characterized by high resolution measurement, but the operating range is normally limited low power light signal. The modulated laser beam is emitted in a continuous manner, so that the power does not exceed the level resulting from safety standards. Devices using the time of flight measurement of the light pulse it possible to achieve a much larger measuring ranges, because the instantaneous power of the light signal is much larger than in the devices measuring the phase shift, however, the resolution of such measurements is generally limited. Rangefinders performing measurement of the phase shift can be divided into another group, namely, laser rangefinders using the so-called modulation optical signal. pseudo-random strings. The use of pseudo-random signals carries a plurality of advantages, such as for example improved resistance to interference unwanted signals or unambiguity of the measurement odległości.W the proposed solution, the remote distance measurement modulates the light output of the laser pseudo-random sequence and outputs it in the direction of the measured object, and the reflected the signal is received with the photodetector converts the optical signal into an electric one. In the remainder of the electrical signal from the photodetector is processed with the help of a single-bit comparator in the digital sequence and subjected to a process called. correlation in a simple digital system.

The essence of the invention is the structure of the correlator and a special selection of the control signals and the clock, making it possible to process information with a simple correlator measured distance. Devices constructed in accordance with the idea of ​​the invention can provide a precise measurement even in a condition in which the received signal is weak, noise and undesired zakłóceń.KorzyściSposób distance measuring device structure and achieves a very high degree of integration of the components, whereby the size of the device can be significantly reduced, and thus it is possible to drastically reduce energy consumption. Despite the low power laser (safety), the potential exists for achieving the measuring range of the order of several dozen meters while maintaining millimeter precision. Moreover, this method of measurement can provide increased immunity to interference. The analog part of the device is very limited, which on the one hand can reduce the cost of production, and on the other hand, reducing the number of components resulting in increased reliability. The proposed method allows measurements to optimize the device parameters and prices for various applications.

If a satisfactory operating range is limited to individual meters, and the resolution of the measurement order of centimeters, it is possible to achieve very low cost produkcji.Potencjał komercjalizacjiPrzedmiotem invention is a method and apparatus for remote distance measurement.
