Among this technique, we use a simple, economical and practical collimation method-single lens collimation method to collimate semiconductor laser beam, and use moving objective scanning method to make laser point scan on the 其中用单透镜准直法对有大发散角的半导体激光光束成功地实现了准直,既简单又经济实用;用平移物镜法实现了激光点的扫描。
Collimate \Col"li*mate\, v. t. [imp. & p. p. {Collimated}; p. p. & vb. n. {Collimating}.] [See {Collimation}.] (Physics & Astron.) To render parallel to a certain line or direction; to bring into the same line, as the axes of telescopes, etc.; to render parallel, as rays of light.
{Collimating eyepiece}, an eyepiece with a diagonal reflector for illumination, used to determine the error of collimation in a transit instrument by observing the image of a cross wire reflected from mercury, and comparing its position in the field with that of the same wire seen directly.
{Collimating lens} (Optics), a lens used for producing parallel rays of light.
