摘要： A calibration apparatus and method for optical system assembly is provided, applicable to a finite conjugate optical system to determine the optimal image-forming positions of the light source and the focus object lens of the finite conjugate optical system. The apparatus includes an external light source, a low magnification image-forming optical system, an electrical control system and a monitor. When the parallel beam generated by the external light source is parallel to the optical axis of the finite conjugate optical system, the low magnification image-forming optical system is used to magnify the two focal spots formed by the external light source and the internal light source of the finite conjugate optical system to be calibrated. Finally, by adjusting the related position of the focus object lens or the internal light source of the finite conjugate optical system, the optimal relative positions between the light source and the focus object lens of the finite conjugate optical system can be found. The calibration apparatus of the present invention has the advantages of simple structure, easy assemble and setup, high precision assembly and low cost, as well as the capability to perform optimal calibration of the relative position of the focus object lens and the light source of each individual finite conjugate optical system.

摘要： The present invention discloses a multiple-beam holographic optical pick-up head, which has the advantages of the multiple-beam optical pick-up head and the holographic optical pick-up head and can increase the light usage efficiency. This invention uses the property that a polarized diffractive optical element can generate different optical effects for laser beam with different polarizations and places a polarized multiple-beam grating and polarized hologram on the optical path for splitting the incident light toward the disc into multiple reading beams by the multiple-beam grating. The returning laser beams reflected from the disc are diffracted and diverted by the hologram to reach a photodetector. Both the incident and reflective beams are diffracted once only; thus the light usage efficiency can be increased.

摘要： A method of forming solar cell includes the following steps. A substrate having a first region and a second region is provided. A dopant source layer is then formed on the substrate. A laser beam is used to locally irradiate the dopant source layer corresponding to the first region to locally diffuse the dopants of the dopant source layer on the first region downward into the substrate. The laser beam also changes the surface property of the substrate in the first region to form a visible patterned mark. The dopant source layer is then removed, and a patterned electrode is formed on the first region of the substrate using the visible patterned mark as an alignment mark.

摘要： In a method of reducing upstream ingress noise in cable data system, downstream management messages containing information about user group data uploading time and channel frequency are broadcasted by a headend of the cable data system. The broadcasted downstream management messages are monitored, so as to determine an upstream channel connection time schedule for the user groups. Each user group is connected to an upstream channel of the headend only at a data uploading time scheduled for that user group. As a result, ingress noise existed in the user group will be uploaded to the headend only when the user group is connected to the headend. Therefore, accumulation of upstream ingress noise at the headend is effectively reduced, and the headend network can maintain good signal quality to ensure best network connection.
摘要翻译：在电缆数据系统中减少上游入口噪声的方法中，包含有关用户组数据上载时间和频道频率的信息的下行管理消息由有线数据系统的前端广播。广播的下游管理消息被监视，以便确定用户组的上行信道连接时间表。每个用户组仅在为该用户组计划的数据上传时间连接到前端的上行信道。因此，只有当用户组连接到头端时，用户组中存在的入口噪声才会上传到头端。因此，前端上游入口噪声的积累有效降低，前端网络可以保持良好的信号质量，确保最佳网络连接。
