Experimental results and values in theory were accordant well. Experimental results showed that the radius of focal spot would increase with the longer focal length, and focal depth would decrease with higher order of FZPs.
实验还发现，聚焦的焦斑半径会随着焦距的长度而增大，而聚焦深度则随着分形波带片的阶次的升高而减小，同时还对比了分形波带片和常规波带片的焦距调节方式和精度，理论研究表明分形波带片的调节焦距的方式具有更高的调节精度。

The lens axicon is based on the use of the spherical aberration of the mirror surfaces,which is inexpensive and easy to manufacture into a element with large apertures as compared with diffractive axicons,refractive cone axicons,and earlier lens axicons with aspheric surfaces;the opaque disk can offer the Bessel beams with long non-diffracting distances,and the diameter of the central peak is adjusted by choosing the focal length of the collimating lens;the tunable fluidic conical lens is a new device for generating Bessel beams,which can obtain the Bessel beams with different parameters by varying the refractive indexes of the solution which is filled in the device.
双透镜轴棱锥法主要基于透镜球面像差的运用，与衍射轴棱锥、折射轴棱锥和早期的非球面轴棱锥相比，具有加工简单、便宜，易于制作大尺寸的特点；不透明障碍物法得到的贝塞尔光束具有很长的无衍射距离，其直径可通过选择不同焦距的准直透镜来得到调节；可调流体轴棱锥是一种产生贝塞尔光束的新型器件，它可以很容易地通过改变注入器件的液体的折射率来得到不同参量的贝塞尔光束。

It allows for versatile adjustment by panning, tilting and rotating the varifocal lens to any camera angle desired.
它还可以对镜头进行水平、垂直及焦距的调节，以满足用户对摄像机视角调节的需要。

focal length：镜头焦距
f值(f-number) 就是镜头焦距(focal length)除以光孔直径的数值(许多人将aperture与diaphragm均称为光圈,是容易造成混淆的,光圈是调节光孔大小的机械构造).

vignetting：渐晕
当然模拟其他胶片规格的相机可以按需要调节.焦距(focal length)和放大系数(zoom factor)都可以调节画面,它们的区别可以看做前者是光学变焦,后者是数码变焦.这里我也把镜头渐晕(vignetting)关掉,因为这里我不需要.一般我只调节快门(shutter speed)来控制胶片的曝光量,
