telecentric beam

According to the third order aberration theory of binary optical element,the optical coupler system with one diffractive surface,telecentric optical path structure in the object space is shown with calculation and optimization of optical design software ZEMAX,whose operating wavelength is(0.

该耦接器采用物方远心光路结构,适用于单丝直径16μm,截面直径为6 mm的光纤传像束。

This paper uses an object telecentric beam path in a diameter measurement system, designs a data acquisition circuit ,and presents a accuracy measure method with polynomial interpolation.

设计了数据采集电路 ,把物方远心光路应用在测径系统中 ,提出了一种利用多项式插值精确测量物体尺寸的方法。
