PROBLEM TO BE SOLVED: To enable accurate measurement of aero-optical disturbances affecting the performance and/or accuracy of optical instrumentation.SOLUTION: A system includes a mirror supported by a gimbal for reflecting a light beam 30 from a light emitting source to a first periscope fold mirror 36 and therefrom reflecting the light beam directly to a second periscope fold mirror 40. A first concave off-axis paraboloid mirror 46 receives the light beam reflected from the second periscope fold mirror. A first fold mirror 42 receives the light beam reflected directly from the first concave off-axis paraboloid mirror. A second fold mirror 44 receives the light beam reflected directly from the first fold mirror. A second concave off-axis paraboloid mirror 52 receives the light beam reflected directly from the second fold mirror, and reflects the light beam to a fast steering mirror 54. A fine tracker camera 41 coupled to an embedded processor 39 receives a portion of the light beam from the fast steering mirror. The embedded processor controls movement of the fast steering mirror and the gimbal.SELECTED DRAWING: Figure 3

    【課題】光学計器類の性能及び/又は正確性に影響を与える航空光学的擾乱の正確な測定を可能とする【解決手段】発光源からの光ビーム30を、第1ペリスコープ折り畳み鏡36へと反射させ、そこから、第2ペリスコープ折り畳み鏡40へと直接反射させるための、ジンバルに支持された鏡を含む。第1凹形軸外放物面鏡46は、第2ペリスコープ折り畳み鏡から反射された光ビームを受容し、第1折り畳み鏡42は、第1凹形軸外放物面鏡から直接反射された光ビームを受容し、第2折り畳み鏡44は、第1折り畳み鏡から直接反射された光ビームを受容する。第2凹形軸外放物面鏡52は、第2折り畳み鏡から直接反射された光ビームを受容し、高速ステアリング鏡54へと反射させる。組み込みプロセッサ39に結合された微細追跡カメラ41は、高速ステアリング鏡から光ビームの一部を受容する。組み込みプロセッサは、高速ステアリング鏡及びジンバルの動作を制御する。【選択図】図3
