Abstract
Some embodiments of the invention may include an electro-optical distance measurement method having at least one emission of a light signal, in particular of laser light, from at least one light source onto a target object, detection of a fraction of the light signal returning from the target object using a detector and a signal processing electronics system connected downstream from the detector, and/or determination of a distance to the target object. In some embodiments, the emitted light signal comprises in this case a sequence of sequential elements of, in each case at least one light pulse and one light signal train. In some embodiments, the light pulses each have a higher intensity amplitude than the light signal trains. Some embodiments may also an electro-optical distance meter having the features analogous to The distance measurement method according to the invention.

16. An electro-optical distance measurement method comprising:
-
emitting a light signal from at least one light source onto a target object; detecting a fraction of the light signal returning from the target object using a detector and a signal processing electronics system connected downstream from the detector; and determining a distance to the target object, wherein; the emitted light signal comprises a sequence of sequential elements of, in each case, at least one light pulse (P(TOF)) and one light signal train (P(Φ
)),wherein the light pulses (P(TOF)) each have a higher intensity amplitude I than the light signal trains (P(Φ
)). - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
