Patent number: 9689970Abstract: Distance measurement methods and apparatus use laser pulse sets having signatures which enable returned pulses to be correlated with emitted pulses. Each pulse set comprises at least one pulse and a signature selected from a set of possible signatures. Pulse sets reflected from at least one surface are detected and, for each set, the signature is recognized and a time of flight is determined. Signatures are defined by one or more of: spacing in time between pulses of a set, wavelength of the at least one pulse of the set, spacing in time between a first subset of a set and a second subset of a set, difference of wavelength between pulses of a set, and difference of wavelength between a first subset of a set and a second subset of a set. Each set can have multiple groups of pulses and pulses within a group can have different amplitudes.Type: GrantFiled: July 1, 2015Date of Patent: June 27, 2017Assignee: Trimble ABInventor: Auguste d'Aligny

Patent number: 9605955Abstract: A distance measuring method includes: emitting a pulse of measuring light towards an object; receiving a pulse measuring light from the object and generating a pulse signal corresponding to the pulse of measuring light received from the object; delaying a first portion of the generated pulse signal for a predetermined time; generating an intensity signal indicative of an intensity of the generated pulse signal, while delaying the first portion of the generated pulse signal; amplifying the delayed first portion of the generated pulse signal using a gain dependent on the generated intensity signal; and determining a value representing a distance based on the amplified delayed first portion of the generated pulse signal.Type: GrantFiled: August 15, 2013Date of Patent: March 28, 2017Assignee: Trimble 3D ScanningInventors: Auguste D'Aligny, Richard Day, Yuri P.

Patent number: 4873449Abstract: The invention relates to process and apparatus for three-dimensional surveying by triangulation with a laser beam source. Pursuant to known practice, a laser beam scans a scene to be surveyed, by means of controlled rotary positioning of a mirror. The reflected beam is detected by a linear array of photosensitive receptors, enabling the location of the illuminated point to be determined by triangulation. Significant to the invention is the use of a secondary light source for precision measurement of the angular location of the scanning mirror, rather than relying upon controlled positioning of the mirror, which is much less accurate.Type: GrantFiled: February 4, 1988Date of Patent: October 10, 1989Inventors: Michel Paramythioti, Auguste d'Aligny
