An altazimuth mount at least has the virtue of simplicity. 地平式支架有简单的优点。
The altazimuth goes up-down (moving in altitude) and side to side (azimuth). 地平式的则是上下、左右运动。
In the paper, the testing scheme and making of a aspheric Ge lens that used in planar wide-angle altazimuth was described. 就平面广角地平仪设计中用到的一块非球面的小型锗透镜作了检验设计和加工。
E.g. the Ge lens used in planar wide-angle altazimuth, indirect ophthalmoscopy lens in ophthalmic diagnosis, Zoom lens of camera, all were minor aspheric component. 例如，红外广角地平仪中的锗透镜、眼科诊断用的间接眼底镜、变焦照相机镜头、刻录机光头等都是小型的非球面元件。
In the test of shooting range , it is called optics measure image which we have gotten images through using optical equipment as film altazimuth -, high speed film equipment -. trajectory camera. 在靶场测试中，利用光学测量设备获得的图像，如电影经纬仪、高速摄影机拍摄得到的胶片图像，弹道相机拍摄得到的干板图像等统称为光测图像。
