高斯光束通过透镜聚焦研究论文

The thesis has explained that matrix optics secretly schemes against in optics field application, as well as fibre-optical is coupled in the optical lens detailedly. Content is included: Alternation matrix , Gauss optics transfer law , the fundamental function of optical lens fibre-optical coupling. Draw forth matrix method in geometrical optics , the ABCD theorem first , adopt the system that the optical lens composes to be a model after the alternation using the person to discuss the Gauss light beam again, how go into chooses the optimum structure parameter, include the width how to choose an optical lens while, high efficiency coupling a use artwork has been explained how to achieve, ensure that minimal connection wastes , as far as possible many energy turn into dodging to launch fibre-optical receive fibre-optical.文章有些长、、望认真看完、、标准人工翻译、、希望可以帮助你、、
