调焦距

与 调焦距 相关的网络例句 [注:此内容来源于网络,仅供参考]

I would use manual focusing to set the lens near its hyperfocal point to maximize depth of field. This will eliminate auto focus delay or hunting, hopefully allowing almost instantaneous shutter release. Do you know if there is a menu that can set the hyperfocal point for you? This would be very useful.

我手动调焦去设置超焦距点附近的透镜取领域的深度最大值,这会除去焦点的延迟或搜索,有希望使瞬间快门线释放~~你知道如果菜单能帮你设定超焦这会非常有用

To improve the performance of zoom systems and achieve a good imaging quality in WFOV, and to simplify the mechanical structure for the convenience of design, process and adjustment, a design concept that combines the conventional spheric optics with the aspheric optics was introduced in the design of zoom lens.

为提高变焦距系统的工作性能,使其在大视场时仍具有良好的像质,且系统结构简单,易于机械设计、加工及装调,在设计中引入了传统球面光学设计与非球面相结合的设计思想。

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。
