STABILIZED DISTANCE MEASUREMENT IN THE OBSERVATION DEVICE
First Claim
1. A portable observation device comprising an observation path, which, in particular, is unstabilized, for optical targeting of a target object, and comprising an optoelectronic rangefinder for measuring the distance in the direction of the targeting, in particular a laser distance meter with a collimated laser beam as a target axis, comprising:
- a transmission unit for emitting a temporal sequence of pulses of optical radiation,a reception unit for receiving a portion of the optical radiation cast back by the target object and for determining signal information of the cast-back portion of an emitted pulse, andan electronic evaluation unit, which is embodied in such a way that a distance to the target object can be determined on the basis of a signal travel time between emission and reception of the optical radiation,wherein the distance is determined including the signal information from a specified minimum number of pulses,which minimum number defines a minimum length of a time window (twd) of the distance measurement, and comprisinga trigger which can be actuated manually and the actuation of which causes a start of the time window (twd) of the distance measurement,whereinthe observation devicecomprises a movement sensor for acquiring an instability of a spatial position of the observation device andan actuation unit of the rangefinder, which is embodied in such a way that the rangefinder is controlled on the basis of spatial position data from the movement sensor in such a way that the pulses counting as part of the minimum number satisfy predetermined criteria in respect of these spatial position data assigned in time.

Abstract
The invention relates to a portable observation device having an observation path for optical targeting of a target object, and comprising an optoelectronic rangefinder for measuring the distance in the direction of the targeting. The rangefinder includes a transmission unit for emitting a temporal sequence of pulses of optical radiation, a reception unit for receiving a portion of the optical radiation cast back by the target object and for determining signal information and an electronic evaluation unit, which a distance to the target object can be determined on the basis of a signal travel time between emission and reception of the optical radiation. When a trigger is actuated manually, the distance is determined including the signal information from a specified minimum number of pulses, which define a minimum length of a time window of the distance measurement.
