There is an aberration Δφ between the phase retardation of the thermal lens and referenced spherical lens.

在rwp時日韩美图精品自拍视频在线观看，ΔΦT相對于參考球面透鏡的相位畸變Δφ隨r的增大而急劇增大。

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.

根據(jù)Sasian的面對稱光學(xué)系統(tǒng)的象差理論无码99riav片，全面分析了球面后視鏡的成象質(zhì)量中老妇女毛片黄片视频。

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.

設(shè)計了四片非球面組成的離軸式反射系統(tǒng)，然而国产免费观看试看免费AV，僅采用非球面設(shè)計系統(tǒng)結(jié)構(gòu)不夠精簡91福利在线播放，性能也有待進(jìn)一步提高，且非球面面形較大時加工和檢測都存在一定的困難手机免费色网址；繼而提出了用球面Fresnel反射鏡代替非球面的設(shè)計方法亚洲人午夜视频，雖然Fresnel反射鏡加工和檢測更為簡單，且復(fù)制成本低又大又长的黄色视频，但對波長具有選擇性91自拍偷拍论坛欧美性爱；進(jìn)而，應(yīng)用折反系統(tǒng)結(jié)合的方式設(shè)計了離軸式投影鏡頭www.18岁禁止网页，該方法因兼具折射和反射的優(yōu)點(diǎn)亚洲视频小说之无码视频，在大屏幕超薄背投系統(tǒng)的設(shè)計中廣為應(yīng)用，缺點(diǎn)是會產(chǎn)生難以校正的色差aaa视频色，且結(jié)構(gòu)復(fù)雜97热在线视频免费播放器。

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.

然后以球差為例，分析了非球面面型系數(shù)與高級像差的關(guān)系久久久久A级毛片免费看，從而為折疊式超薄光學(xué)系統(tǒng)的像差平衡提供依據(jù)九九视频九九视频在线。

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.
