Abstract: The present invention provides a reflective condensing interferometer for focusing on a preset focus. The reflective condensing interferometer includes a concave mirror set, a convex mirror, a light splitting element, and a reflecting element. The concave mirror set has first and second concave surface portions which are oppositely located on two sides of a central axis passing through the preset focus and are concave on a surface facing the central axis and the preset focus. Light is preset to be incident in parallel to the central axis in use. The convex mirror is disposed between the concave mirror set and the preset focus on the central axis, and is convex away from the preset focus. The light splitting element vertically intersects with the central axis between the convex mirror and the preset focus. The reflecting element is disposed between the light splitting element and the convex mirror.

Abstract: A method for deploying a computer operating environment and a deployment system are provided. A template machine is provided. A deployment program is executed in the template machine for scanning data of an operating system and applications in the template machine. The data are segmented into multiple segments and then encoded. An index and a checksum for each of the segments called metainfo are created. The metainfo is distributed to terminal machines within a network domain. After receiving the metainfo, every terminal machine obtains the segments, decodes the segments, and verifies the correctness of the received segments with the checksum. When requested by other terminal machines, the terminal machine reads the specific segments and then distributes those to the other terminal machines via a peer-to-peer data sharing protocol. The deployment is completed after all of the segments of operating environment are written in the terminal machine.
