摘要： A single lens homogenizer for converting a wide, parallel, in-phase Gaussian beam into a narrow uniform-power beam and shooting an object with the narrow uniform-power beam is proposed. A tilt error induces beam deformation. A single lens homogenizer which can reduce the beam deformation induced by the tilt error is proposed. A suitable homogenizer is a convex/flat lens having a convex aspherical surface on the light source side and a flat surface on the object side. Another preferable homogenizer is a convex/convex lens having a convex surface on the light source side and a convex surface on the object side. At least one of the convex surfaces is an aspherical convex surface.

摘要： In a diffractive optical element (DOE) of diffracting a Gaussian distribution beam into a uniform or quasi-uniform power distribution beam on an image plane, step height errors or other manufacturing errors yield a zero-th order beam, cause interference between the diffracted beam and the zero-th order beam and invite power fluctuation. Instead of a parallel planar shape, a wedge-shaped DOE having surfaces inclining at an angle Θ in average separates the zero-th order beam from the diffraction beam, prevents the zero-th order beam from interfering with the diffraction beam and suppress power fluctuation of the diffraction beam. The wedge angle Θ satisfies an inequality Θ≧{+(D/L)}/(n−1), where D is a diameter of the incident beam, n is a refractive index of the DOE, L is a distance between the DOE and the image plane, and is an angle viewing the uniform power pattern on the image plane from the center of the DOE.
摘要翻译：在将高斯分布光束衍射到图像平面上的均匀或准均匀功率分布光束的衍射光学元件（DOE）中，步长高度误差或其他制造误差产生零级光束，导致衍射光束和零级波束，并引起功率波动。代替平行平面形状，具有以角度θta倾斜的表面的楔形DOE平均将零级光束与衍射光束分离，防止零级光束与衍射光束干涉并抑制功率波动的衍射光束。楔角Theta满足不等式Theta> = { +（D / L）} /（n-1）其中D是入射光束的直径，n是DOE的折射率， L是DOE和图像平面之间的距离，是从DOE中心观看图像平面上的均匀功率图形的角度。
