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.

Stabilized distance measurement in the observation device

The invention relates to an optoelectronic distance measuring device having a transmitting unit having a driver stage for a light source for emitting optical pulses as pulsed-mode-intensity-modulated optical radiation, having a receiving unit for receiving a portion of the optical radiation, said portion being reflected from a target object, and converting it into an electrical reception signal, by means of a photosensitive electrical component. It also has an analogue-digital converter for digitizing the reception signal, and an electronic evaluation unit which is designed in such a way that a distance from the target object can be ascertained on the basis of a signal propagation time using the digitized reception signal.

Distance measuring device

An optoelectronic distance measuring device is disclosed. The device has a transmitting unit with a driver stage for emitting optical pulses, a receiving unit for receiving a portion of the optical pulses, said portion being reflected from a target object, and converting it into an electrical reception signal, via a photosensitive electrical component. It also has an analog-digital converter for digitizing the reception signal, and an electronic evaluation unit to ascertain a distance from the target object on the basis of a signal propagation time using the digitized reception signal. The driver stage can be designed so that at least two pulse durations of different length for the optical pulses can be set.

The invention relates to an electro-optical distance measuring device comprising a transmitting unit comprising a light source for emitting intensity-modulated optical radiation, a receiving unit for receiving a portion of the optical radiation, said portion being reflected from a target object, by means of a photosensitive electrical component and for converting it into an electrical reception signal. Furthermore comprising a conditioning unit for conditioning the reception signal comprising at least one amplifier stage, an analog-to-digital converter fox digitizing the conditioned reception signal, and an electronic evaluation unit, which is designed in such a way that a distance from the distance measuring device to the target object, can be determined on the basis of a signal propagation time with the aid of the digitized reception signal. According to the invention, in this case the amplifier stage is designed in such a way that it has a non-linear input-output characteristic.
