    Abstract: A system and method of generating a two-dimensional image of an environment is provided. The system includes a 2D scanner that comprises a light source, an image sensor and a controller. The controller determines a distance value to at least one of the object points. An inertial measurement unit is coupled to the scanner and has a first sensor. The first sensor has a first characteristic. A mobile computing device is removably coupled to the 2D scanner, the mobile computing device having a second sensor, the second sensor having a second characteristic. Processors are provided that are responsive to compare the first characteristic and the second characteristic and select one of the first or second sensor based on the comparison. The processors are further generate an image of the environment based on a signal from the selected first or second sensor.

    Abstract: A method for optically communicating, from a user to a laser tracker, a command to direct a beam of light from the laser tracker to a retroreflector with steps including: projecting a first light from a light source disposed on the laser tracker to the retroreflector; reflecting a second light from the retroreflector, the second light being a portion of the first light; obtaining first sensed data by sensing a third light, the third light being a portion of the second light, wherein the first sensed data is obtained by imaging the third light onto a photosensitive array disposed on the laser tracker and converting the third light on the photosensitive array into digital form; generating by the user, between a first time and a second time, a predefined temporal pattern, the predefined temporal pattern including at least a decrease in optical power of the third light followed by an increase in the optical power of the third light, the predefined temporal pattern corresponding to the command; determining by the laser tracker that the first sensed data corresponds to the predefined temporal pattern; and, pointing the beam of light from the laser tracker to the retroreflector.

    Abstract: Imaging devices and mirror assemblies for imaging devices are provided. The mirror assemblies include a first portion having a first cut face and formed of a transparent material, a second portion having a second cut face and formed of the transparent material, wherein the second cut face is assembled to the first cut face form a main body, and at least one reflective surface positioned between the first and second cut faces.

    Abstract: A safety sensor system and method is provided. The method includes projecting from a projector a pattern of light to a first position. The pattern of light being generated by a shape control element with each of the first pattern of light having a pattern pose. A first image is captured with a camera of the first pattern of light. The pose or shape of the pattern of light is changed using the shape control element. A pattern pose or shape information is determined from both images. It is determined that the second image is valid based on the pattern pose or shape information differing by more than predetermined measurement errors or the pattern pose or shape information differing less than predetermined measurement errors from values that are based on the control values transmitted to the pattern pose and shape control element.
