光栅用在高斯光束参数测量中的突出优点是方法简单，成本较低。全息光栅由于其制备容易、无周期误差而比一般光栅具有更多的优点。在用光栅进行光斑测量的实验中，观察到由全息光栅引起的泰伯（Talbot）效应携带了有关光斑参数的有用信息。本文提出了一种基于泰伯效应的测量方法，只需测定条纹间隔就能确定高斯光束尺寸，因此降低了对光源或光栅定位精度、电路和光源稳定性的要求。文中就聚焦高斯光束照明全息光栅时光场分布，及其用于高斯光束参数测量的可能性作了分析，理论分析、计算机模拟和实验结果取得了较好的一致。
The outstanding advantages of using a grating in Gaussian beam parameter measurement are its simplicity and low cost. Holographic gratings have more advantages than conventional gratings due to their ease of preparation, no periodic errors. In the experiment of grating speckle measurements, it was observed that the Talbot effect caused by holographic gratings carries useful information about speckle parameters. In this paper, a method based on Talbot’s effect is proposed. The Gaussian beam size can be determined only by measuring the stripe interval, thus reducing the requirements on the positioning accuracy of the light source or grating, the stability of the circuit and the light source. In this paper, the distribution of the light field when the Gaussian beam illumination holographic grating is focused on and the possibility of measuring the Gaussian beam parameters are analyzed. The theoretical analysis, computer simulation and experimental results are in good agreement.
