摘要:
An apparatus for precise distance measurement has a multiple frequency generator, a laser transmitter, an optical receiver, a first measuring unit, a second measuring unit and a central processing unit. The laser transmitter outputs a light signal to a target, and the optical receiver receives the reflected light signal and mixes the base frequency signal from the multiple frequency generator and the reflected light signal and further outputs an measurement signal to the first and second measuring units. The first and second measuring units calculate respectively a time difference and a phase difference between the light signal and the reflected light signal. The central processing unit is connected to the first and second measuring units to calculate a precise distance by the time and the phase difference.

A method of measuring the azimuth and resetting to zero azimuth automatically is disclosed. Multiple azimuths in longitudinal and latitudinal orientations are sampled by two orthogonal magnetic sensors installed in an azimuth meter, and then are output by corresponding first and second sine wave signals. These two sine wave signals are normalized by adjusting them to be of equal amplitude. The maximum and minimum values of the normalized sine wave signals are used to compute the average values of the respective normalized sine wave signals being of equal amplitude on the positive and negative sides. The resultant sine wave signals serve as the zero reference values for comparison with subsequently taken measuring signals to yield the actual azimuth. The numerical computation for the azimuth can be performed by a microprocessor with accuracy and high speed.

A Rangefinder capable of long and short distance measurement in company with compass measurement. The rangefinder includes distance measurement unit, a compass sensing unit and a processor. The rangefinder can selectively execute a comparison mode or a gain mode. The comparison mode is executed during short-distance measurement and the gain mode is executed during long-distance measurement. The compass measurement unit senses a terrestrial magnetism to obtain first and second magnetic sensing signals. The processor estimates a distance between the target and the rangefinder according to the measurement signal from the distance measurement unit and determines a compass orientation of the target according to the first and second magnetic sensing signals.
