Far-field Divergence Angle Measurement of Gaussian Beam Based on Wedge Plate Shearing Interference 基于楔板剪切干涉的高斯光束远场发散角测量斑纹切位变干涉测定
When the angle of an air wedge which is formed by two flat glass plates is changed, the moving interference fringes would be observed by means of CCD. 当用两块平板玻璃制作出的空气劈尖顶角发生变化时,应用CCD可观察到劈尖表面移动的干涉条纹。
The relation between the alignment error and the angle of the air wedge is educed and used to evaluate the object ′ s alignment error with the least envelop area method. The result is 8.11 ±( 0.62 μ m.) 由导出的直线度误差与空气劈尖顶角之间的关系,用最小包容区域法对工件的直线度误差进行了评定,评定结果为8.11±0.62μm。
For a wedge subjected to tractions in proportion to r(?) ( n ≥ 0), the stresses of the solution in classical theory of elasticity become infinite when the angle of the wedge to π or 2 π. 对于一个楔,当其表面受有与r~n(n≥0)成正比的外载荷时,按照经典弹性力学的解,对于顶角2α为π或2π的楔,其应力为无限大。
The influence of aperture angle for illumination light on uniformity of the color splitting system is discussed and a color aberration correction by means of wedge coating with. gradient thickness is proposed, thus the color uniformity can be obviously improved. 讨论了照明光孔径角对分色系统色均匀性的影响,提出了用厚度渐变的楔形膜校正色差的方法,使色均匀性得到显著改进。
