Based on the Sasians aberration theory of a bilateral symmetric optical system, the image quality of a rear view mirror with a spherical surface is studied comprehensively.

根据Sasian的面对称光学系统的象差理论,全面分析了球面后视镜的成象质量。

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统,然而,仅采用非球面设计系统结构不够精简,性能也有待进一步提高,且非球面面形较大时加工和检测都存在一定的困难;继而提出了用球面Fresnel反射镜代替非球面的设计方法,虽然Fresnel反射镜加工和检测更为简单,且复制成本低,但对波长具有选择性;进而,应用折反系统结合的方式设计了离轴式投影镜头,该方法因兼具折射和反射的优点,在大屏幕超薄背投系统的设计中广为应用,缺点是会产生难以校正的色差,且结构复杂。

Secondly, according to the aberration balancing, the relationship between coefficient of conicoid and high-order spherical aberrations was presented, which can support the design of advanced performance folded lens.

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。
