激光準直儀激光準直儀laser collimator iiguang Zhunzhiyi激光準直儀(laser Collimator)利用激光束標定直線的儀器。通常由激光發射系統和光電檢側系統組成。其原理是:利用激光的方向性好、發散角小、亮度強等特點，通過望遠鏡作定向發射，在空間形成一條光束作為準直的墓準線。分為激光經緯儀準直和波帶板激光準直。激光經緯儀準直，由望遠鏡發射器和光電檢測器(光電接收靶)組成。激光通過望遠鏡發射，調節焦距使光束能在接收靶上形成較小的光斑，在需要準直的點上用光電檢測器觀測光斑能量中心，以測定各點偏離基準線的偏差值。激光束受本身的漂移和大氣條件的影響，準直精度約為長度的10一5一10一“。用于軍用坑道和飛機洞庫等地下工程開挖、管道敷設、建筑物施工等。波帶板激光準直儀，由激光器點光源、波帶板裝置與光電接收靶組成。測量時，在基準線兩端點上分別安置激光器和接收靶，在中間需要準直的點上安置波帶板，激光器l掖光源發射出一束激光，照射到波帶板，在接收處由于光干涉作用聚焦形成亮點或亮十字線。根據光的衍射原理，激光發射中心、波帶板中心及成像光斑中心將構成一條直線。三點準直克服了漂移，能提高準直精度，若讓激光束穿過真空管道，還可克服大氣折射影響，準直精度達長度的10一7。用于軍事工程長距離精密準直測量，例如導彈發射用的火箭橇軌道、高能粒子對撞機直線加速器、大型機械設備軸線安裝及建筑物變形觀測等。 (于來法)
