reflecting grating

基本解释

A reflecting hologram diffraction grating was fixed to the stage to form a closed loop displacement measuring system.
固定在工作台上的全息衍射光柵實現了對工作台位移的高精度閉環檢測。
The theory and experiment techniques about measuring the thermal diffusivity of solid materials by using laser induced transient reflecting grating is introduced.
闡述了用脈沖激光引發瞬態熱反射柵的方法來測量固躰材料熱擴散率的理論、實騐裝置和實騐技術。
As a sensor element, fiber optic and grating transformed the information into reflecting wavelength shift. It also named wavelength demodulation which is immune for light power waving and system loss.
作爲傳感元件，光纖光柵將被測的信息轉化爲其反射波長的移動，即波長解調，因此不受到光功率波動和系統損耗的影響。
