解釋
束記錄-
Therefore, the three fundamentals required to obtain high precise measurements are : 1 ) frequency stability and frequency difference stability of the double - frequency laser source as well as the stable equivalent length of bore ; 2 ) the measuring beam and the reference beam are placed very co - axially ; 3 ) capability of recording the sub - division of the period of phase change and a reversible counter system
因而干涉儀系統達到高精度的基礎是：頻率及頻差穩定的雙頻激光源、穩定的等效腔長；測量光與參考光合光後有很高同軸度的光路結構；能可靠記錄相位差變化周期數的細分及可逆計數系統三部分。 -
The recording system has been formed as in - line holography and only a single beam is used for recording, so an antivibration arrangement is not required
該記錄系統僅需一束照明光束，記錄過程不需特定的防震裝置。 -
The experiment results show that there are optimal defocus distance and exposure for the given system and recording material, and to obtain the best snr different reference - to - object beam ratios are also needed for black - white digital images of different space frequencies
實驗結果表明，對于給定的系統及記錄介質存在一定的最佳離焦量和曝光量，而對于不同空間頻率的黑白二值條紋圖像還需要採用不同參?物光比以最終獲得最佳的信噪比。 -
