摘要： A calibration method and a calibration device based on single-wavelength double-laser-tube phase measurement are disclosed. The calibration method includes: (S1) generating an external light path via a laser automatic power control circuit through a high frequency modulation signal, sending the external light path to a measured target, reflecting the external light path back through the measured target and receiving the reflected external light path by a photoelectric receiving circuit; (S2) generating an internal light path via the laser automatic power control circuit through the high frequency modulation signal, directly sending the internal light path to the photoelectric receiving circuit, and receiving the internal light path through the photoelectric receiving circuit; and (S3) performing phase comparison between two paths of light waves respectively corresponding to the external light path and the internal light path which are received firstly and secondly by the photoelectric receiving circuit, and a reference phase signal through the photoelectric receiving circuit, calculating a distance phase, and outputting a signal whose base is eliminated. By means of the method, the phase error is compensated and calibrated, so that the effect of environmental factors on the distance measurement error is reduced, thereby improving the distance measurement precision of the laser ranging, and improving the distance measurement stability of the system.

摘要： In one general aspect, an apparatus can include a first laser subsystem configured to transmit a first laser beam at a first location on an object at a time and a second laser subsystem configured to transmit a second laser beam at a second location on the object at the time. The apparatus can include an analyzer configured to calculate a first velocity based on a first reflected laser beam reflected from the object in response to the first laser beam. The analyzer can be configured to calculate a second velocity based on a second reflected laser beam reflected from the object in response to the second laser beam. The first location can be targeted by the first laser subsystem and the second location can be targeted by the second laser subsystem such that the first velocity is substantially the same as the second velocity.

摘要： A method is provided for illuminating an object and for determining a distance value R. The object is illuminated with a light source and the light intensity of the light source is switched at a time T0 from an intensity Iout,h to an intensity Iout,l being lower than Iout,h and switched back to Iout,h at a time T0+Tn. A signal value U is outputted at the end of an integration window time period which has such a predetermined delay relative to T0 that either Ttof or Ttof+Tn is between an integration start point in time Tsd of the integration window time period and an integration end point in time Tsd+Ts, with Ttof being a point in time when light with the intensity Iin,l arrives first at the photo element, and Ts is longer than Tn.

摘要： In an apparatus using an intensity-modulated light for detection of spatial information based upon light intensity of light reflected from a target space, a timing synchronization circuit is provided to synchronize a phase of the intensity-modulated light from a light-emitting element with a timing of operating a light-receiving element receiving the intensity-modulated light. The light-receiving element is caused to operate for enabling the detection of intensity of the received light for each of a plurality of phase regions within one cycle of the intensity-modulated light. The timing synchronization circuit functions to compare a cyclic variation determining the operation of the light-receiving element with a cyclic variation associated with an output from a light-emitting element driving circuit in order to keep a constant phase difference between these two cyclic variations.
