Patent number: 8611022Abstract: An optical receiver lens has a three-dimensional lens surface, for receiving the laser radiation of a laser distance measuring device, said laser radiation being reflected at an object, wherein the receiver lens can be described in a three-dimensional coordinate system having three axes x, y, z arranged at right angles with respect to one another and wherein the z-axis coincides with the optical axis of the receiver lens. At least one non-spherical area section of the lens surface can be described by addition of a first area, the flexure of which along the z-axis is a first function (f1) of x and y, in particular of (I) and a second area, the flexure of which along the z-axis is a second function (f2) of x and not of y. A distance measuring device is also described.Type: GrantFiled: October 20, 2009Date of Patent: December 17, 2013Assignee: Robert Bosch GmbHInventors: Matthieu Richard, Cedric Pahud, Bjoern Haase

Patent number: 7843553Abstract: The invention is based on a distance-measuring device, in particular a laser distance-measuring device (10) which is in the form of a handheld device, having a printed circuit board (18) and a transmitting or receiving unit (20, 22) which is provided for transmitting or receiving a measurement signal, and comprises a housing (30, 46, 82, 96, 130) which has a base surface (32, 48, 102, 140) which faces the printed circuit board (18), a side surface and a signal surface (38, 50, 98, 142). The invention proposes that the side surface is in the form of a signal surface (38, 50, 98, 142).Type: GrantFiled: June 22, 2006Date of Patent: November 30, 2010Assignee: Robert Bosch GmbHInventors: Uwe Skultety-Betz, Bjoern Haase, Joerg Stierle, Peter Wolf, Cedric Pahud, Kai Renz, Clemens Schulte

Patent number: 7826040Abstract: The invention relates to an electro-optical measuring device, in particular a hand-held device (10) for contactless distance measurement, comprising an optical transmission path (28), which has a first optical axis (72) and which has at least one optical transmitter (20) for emitting a measurement signal, and also comprising a reception path (29) having a second optical axis (74), which is spaced apart from the first optical axis (72), with at least one reception optic (32) for focusing a measurement signal in the direction of a receiver (26), and also comprising an optical near range element (60) for parallax compensation. It is proposed that the near range element (60) be embodied rotationally symmetrically with respect to the second optical axis (74).Type: GrantFiled: July 25, 2006Date of Patent: November 2, 2010Assignee: Robert Bosch GmbHInventors: Peter Wolf, Uwe Skultety-Betz, Gunter Flinspach, Clemens Schulte, Joerg Stierle, Cedric Pahud, Bjoern Haase, Kai Renz

Patent number: 7751033Abstract: The invention relates to a method for measurement of a line (S), in particular, an optical distance measurement method, whereby an input means (24,42) of a distance measuring device (20,22) is operated, which triggers a measuring sequence of distance measurements, during which individual measurements (10-16) of distances from the distance measuring device (20,22) triggered by the distance measuring device (20,22) are carried out perpendicular to the line (s) for measurement. According to the invention, at least one maximum value (10,16) and at least one minimum value of the distances are determined from the measuring sequence and the length of the line (s) determined from the at least one maximum value (10,16) and the at least one minimum value (13). The invention further relates to a distance measuring device (20,22), in particular, a hand-held measuring device for carrying out said method.Type: GrantFiled: December 7, 2005Date of Patent: July 6, 2010Assignee: Robert Bosch GmbHInventors: Uwe Skultety-Betz, Bjoern Haase, Joerg Stierle, Peter Wolf, Gunter Flinspach, Cedric Pahud, Kai Renz, Clemens Schulte

Patent number: 7728957Abstract: The invention relates to a device for optical distance measurement, in particular a device functioning in accordance with the phase measurement principle, having at least one transmission unit (12) equipped with at least one light source (22, 24) for transmitting modulated optical measurement radiation (16) toward a target object (20), and having a reception unit (18) for receiving the optical measurement radiation (17) returning from the target object (20). According to the present invention, the device has means (51, 55, 68) that enable a measurement of distances from a target object (20?) by means of a triangulation method. The invention also relates to a method for optical distance measurement in which it is possible to switch back and forth between a phase measurement method for determining a distance of a distance measuring device from a target object (20, 20?) and a triangulation method for determining this distance.Type: GrantFiled: July 1, 2005Date of Patent: June 1, 2010Assignee: Robert Bosch GmbHInventors: Bjoern Haase, Joerg Stierle, Peter Wolf, Cedric Pahud, Kai Renz, Clemens Schulte
