本专利阐述了风洞检验中结构部分旋转角度的遥测方法。这种角位移测量装置采用了从一个激光器发出的多元偏振光束。每束光随着结构可运动的元件旋转。多元光束通过计算机连入一个由可旋转偏振器与成对探测器集成的系统。计算机使信息数字化并作
This patent describes the telemetry method of structural part rotation in wind tunnel inspection. This angular displacement measurement device uses a multi-polarized light beam emitted from a laser. Each beam of light rotates with the structure-movable element. Multiple beams are computer-connected to a system of rotatable polarizers and paired detectors. Computer digitizes information and makes it
