Instrument arrangement consisting of a laser transmitter, day channel and thermal-imaging channel

摘要

When being assembled, the instrument arrangement (5), which consists of a laser transmitter (3), day channel (4), thermal-imaging channel (1) and observing channel (2), can be harmonized with respect to its optical axes (34, 33, 18, 33', 18') with the single collimating mark (17). The radiation (8) received and rendered visible in the thermal-imaging channel is brought together with the collimating mark with the aid of a first prism arrangement (14). From here, the radiation and collimating mark pass over a second prism arrangement, provided with a variable gap (38), of the observing channel (2) to the eyepiece (31). By contrast, when the gap is closed the radiation of the day channel (4) is directed on to the eyepiece via a second pair of rotating wedges (26) serving to adjust this radiation to the collimating mark (17). A third pair of rotating wedges (35) which adjusts the laser transmitter is synchronously co-adjusted in this connection via deviation voltages of the second pair of rotating wedges and the electrical position transducer (36). <IMAGE>
