Device for optically scanning and measuring an environment
First Claim
1. A device for optically scanning and measuring an environment, comprising:
- a laser scanner having a light emitter that emits an emission light beam, the laser scanner also having a rotary mirror, the laser scanner further having a light receiver that receives a reception light beam, where the emission light beam is reflected by the rotary mirror to an object in the environment, where a portion of the emission light beam is reflected by the object to produce the reception light beam, and where the reception light beam is reflected by the rotary mirror and passes through a receiver lens which has an optical axis, is reflected from an object in the environment of the laser scanner;
the laser scanner also having a control and evaluation unit which, for a multitude of measuring points, determines a distance to the object; and
the laser scanner further having a rear mirror located on the optical axis behind the receiver lens, where the rear mirror reflects the reception light beam, which has been refracted by the receiver lens, towards the receiver lens.

Abstract
In a device for optically scanning and measuring an environment, where the device is a laser scanner having a light emitter which, by a rotary mirror, emits an emission light beam, with a light receiver which receives a reception light beam, which, after passing the rotary mirror and a receiver lens which has an optical axis, is reflected from an object in the environment of the laser scanner. The laser scanner also includes a control and evaluation unit which, for a multitude of measuring points, determines the distance to the object. Also, a rear mirror is provided on the optical axis behind the receiver lens, where the rear mirror reflects towards the receiver lens the reception light beam which is refracted by the receiver lens.
