The normal incidence broadband spectroscopic polarimeter can make the probe beam normal incidence and focus on the sample surface by using at least one flat reflector element to change propagation direction of the focused beam. Moreover, the normal incidence broadband spectroscopic polarimeter contains at least one polarizer as to measure the anisotropy or non-uniform samples, such as three-dimensional profile and material optical constants of thin films consisting of the periodic structure. An optical measurement system including the normal incidence broadband spectroscopic polarimeter is also provided.

摘要： An oblique incidence broadband spectroscopic polarimeter which is easy to adjust the focus, achromatic, maintains the polarization and has simple structure is provided. It comprise at least one polarizer (P, A), at least one curved reflector element (OAP1, OAP2, OAP3, OAP4) and at least two flat reflector elements (M1, M2). By utilizing the flat reflector element, the oblique incidence broadband spectroscopic polarimeter can change the propagate direction of beam, and compensate the polarization changes caused by the reflective focusing unit, make the polarization of beam passed the polarizer unchanged when obliquely incident and focus on the sample surface. The oblique incidence broadband spectroscopic polarimeter can accurately measure the optical constants of sample material, film thickness, and/or the critical dimension (CD) properties or three-dimensional profile for analyze the periodic structure of the sample. An optical measurement system including the oblique incidence broadband spectroscopic polarimeter is also provided.

摘要： A technical solution for accurately positioning a computer position, that is to say, the solution can identify the specific rack position where the computer is. And the solution has low cost and does not need manual intervention. The core idea of the solution lies in using a camera installed on the computer to read the contents of a tag on the rack, so as to identify the position information of the computer. Specifically, the solution provides a computer with a self-positioning function, wherein: a camera is installed on the computer, and the camera is configured to read the contents of a tag attached on a side of a rack to house the computer to identify the rack position where the computer is.
