To avoid the occurrence of a dead angle caused by a delay in the rotation around an azimuth axis.SOLUTION: An orientation tracking device according to the present disclosure includes: an arm-type support structure which is connected rotatably around an azimuth axis to a base structure; a barrel which has an aperture being a transmitting/receiving port for laser beams and is held by the arm-type support structure rotatably around an elevation axis with respect to the arm-type support structure; a prism which has an optical axis inclined relative to the central axis of the aperture and is attached to the barrel rotatably around the central axis of the aperture; and a control processing device which controls the rotation angles of the arm-type support structure, the barrel, and the prism so that the laser beam passing through the prism tracks the trajectory of a target object in the sky.SELECTED DRAWING: Figure 1
【課題】アジマス軸まわりの回転の遅れによる死角の発生を回避する。【解決手段】本開示の指向追尾装置は、ベース構造物に対してアジマス軸まわりに回転可能に接続されたアーム型支持構造物と、レーザービームの送受信口である開口部を有し、前記アーム型支持構造物に対してエレベーション軸まわりに回転可能に前記アーム型支持構造物に保持された鏡筒と、前記開口部の中心軸から傾斜した光軸を有し、前記開口部の中心軸まわりに回転可能なよう前記鏡筒に取り付けられたプリズムと、前記プリズムを通る前記レーザービームが上空の目標物体の軌道に追従するように、前記アーム型支持構造物、前記鏡筒、及び前記プリズムの回転角を制御する制御処理装置と、を備える。【選択図】図1
