A frame for a scanning device includes a supporting device for fitting and carrying the frame by a person. The supporting device has a shoulder rest for placing the frame on the person's shoulders. The frame further includes an upper frame section, to which a first holder for the scanning device is fastened, with the first holder located above the person's head when the person is carrying the frame by means of the supporting device. The frame further has a contact part which is connected via a bracket to the shoulder rest, with the contact part located at the level of the person's hip region when the person is carrying the frame by means of the supporting device. A spatial detection device includes a scanning device and a frame.

Frame for at least one scanning device and spatial detection device with at least one scanning device

A mobile apparatus for capturing an object space includes a frame and at least one single scanner mounted on the frame and a multiple scanner mounted on the frame above the single scanner. This multiple scanner has a plurality of emission units integrated in one component, a receiver for detecting reflected rays, and a scanning device for changing the emission directions of the signal beams of the emission units. Furthermore, the mobile apparatus has an evaluation device which is designed to generate and output in real time, at least from the reflected rays detected by the receiver, a graphical representation of those areas of the object space through which the mobile apparatus can be moved and/or has been moved. Finally, the mobile apparatus has a data interface designed to output data to a memory device for post-processing. A corresponding method for capturing an object space is also disclosed.

Mobile apparatus and method for capturing an object space

The lidar arrangement (1) has a transmitter (3) for linearly polarized radiation (12), a receiver (5) with a first receiving device which measures intensity of the backscattered radiation (15) coinciding approximately with the transmitted radiation cone (12) in a polarization plane of the cone and in a perpendicular polarization plane, wherein the receiver further includes a second receiving device which measures the intensity of backscattered radiation (17) outside the transmitted cone (12), the outer backscattered radiation has the shape of a conical shell which surrounds the backscattered conical shell of the first mentioned backscattered radiation (15) and of the transmitted cone (12); the received separate radiation cones (15 and 17) are split in a polarization analyzing optical element into two mutually perpendicular partial light beams, each consisting of an inner partial beam portion (15a, 15b) and an outer partial beam portion (17a and 17b), the inner and outer partial beam portions are separately detected and the resulting output signals are amplified by an amplification factor which depends on the distance of the lidar from a visibility obstacle, the distance-corrected amplified signals are evaluated in a signal processing unit to distinguish between different kinds of the visibility obstacle, and the evaluated obstacle such as fog, rain, snow or solid obstacle and a distance thereof are indicated on corresponding indicators.

Lidar arrangement for measuring atmospheric turbidities

A method and device is provided for determining the direction and speed of wind in the atmosphere by means of a laser-Doppler anemometer, wherein only values measured in a sector of about 100.degree. and less of an azimuth scan are supplied or fed to a multiple-peak finder of a measuring device. In order to attain a high processing speed, flowing differentiation takes place by means of digitally operating systems. In order to eliminate the influences from clouds, haze, fog and the like in the measuring device, several frequency maximums are always traced in the multiple-peak finder, whereby in each case a preceding maximum is related to a trailing maximum until the trailing maximum is smaller than the preceding maximum. Because of the attainable high-speed sector scanning, the measuring device can be used for the determination of multiple wind peaks caused by clouds and/or fog echoes, or at an installation site where the measuring range is highly restricted, or also for detecting aircraft wake vortices.

Method for determining the direction and speed of wind in the atmosphere

A laser echoe ranging device (lidar) is used both to measure cloud height and to measure slant range visibility. For the latter purpose at various elevation angles, the distance for which the echoe gets down to the noise level is measured by a counter and the echo voltage for a distance selected by a time switch is also stored, for example for various distances in 100 meter steps. These values can be used to compute the slant visual range and, with reference to the data for the different angles of elevation, also the layer structure of an inhomogeneous scattering characteristic of the atmosphere.
