The imaging lens housing (157) provides an apron (300) which increases ESD discharge path length.

成象镜头外壳提供一裙（300），它增大了ESD放电的路径长度。

Volume holographic grating, used as a volume holographic imaging lens in the imaging system, is recorded via illuminating the recording medium with a spherical signal beam and a plane reference beam.

体全息光栅由球面信号光波和平面参考光波干涉记录，并以原信号光作为探测光波进行成像。

As an imaging tool, the acoustic lens beats ultrasound imaging because the sound pulses can be focused much more tightly and can be easily repositioned.

作为一个成像工具，声透镜冲击了超声波的显像，因为声脉冲可以更加紧密地聚焦，可以很容易地重新定位。

The imaging characteristics of a GRIN fiber lens with exponential variation of the constant-index surfaces are discussed based on the ray paths equations.
