First Claim
Patent Images
1. A laser scanner for optically scanning and measuring an object in an environment, the laser scanner comprising:
- a light emitter configured to emit an emission light beam, an electromagnetic energy generator configured to emit a first electromagnetic energy, and a first beam splitter configured to combine the emission light beam with the first electromagnetic energy in a combined light and to send the combined light out of the laser scanner into the environment;
an optical system including at least one of a reflective optical component and a refractive optical component, the optical system receiving in operation a combined reflected light, the combined light reflected by the object and received by the at least one or a reflective optical component and a refractive optical component;
a second beam splitter configured to separate the combined reflected light into a reflected emission light and a reflected electromagnetic energy;
an optical receiver having a collecting lens and a detector, the optical receiver determining in operation a distance to a point on the object based at least in part on the reflected emission light with the detector;
a spectrometer receiver having a photosensitive detector that receives in operation the electromagnetic energy, the spectrometer receiver determines in operation a wavelength spectrum of the reflected electromagnetic energy received by the photosensitive detector; and
a control and evaluation unit having a processor and a data connection to the light emitter and the light receiver, the processor determining in operation a distance from the laser scanner to the point on the object, the determined distance based at least in part on a propagation time of the emission light beam and the reflection light beam.
