    • A surface plasmon resonance meter is provided, including a backlight module, a line-slot plate, a parabolic mirror, a linear polarizer, a sensing chip, a prism and a photo detector array. The line-slot plate includes a light outlet. A light beam travels in the backlight module, and leaves the backlight module through the light outlet. The position of the line-slot plate is matched on a predetermined focal point of the parabolic mirror. The light beam is reflected by the parabolic mirror to be a parallel light beam, and travels trough the linear polarizer to the prism. The prism includes a light entering surface, a detection surface and a light exiting surface. The light beam enters the prism through the light entering surface, contacts the sensing chip with total internal reflection, and finally leaves the prism through the light exiting surface to be received by the photo detector array.
    • 提供了表面等离子体共振仪,包括背光模块,线槽板,抛物面镜,线性偏振器,感测芯片,棱镜和光电检测器阵列。 线槽板包括一个灯出口。 光束在背光模块中传播,并使背光模块通过灯泡出口。 线槽板的位置在抛物面镜的预定焦点上匹配。 光束被抛物面镜反射成平行光束,并且通过线性偏振器行进到棱镜。 棱镜包括光入射表面,检测表面和光出射表面。 光束通过光进入表面进入棱镜,与全内反射接触感测芯片,最后通过光出射表面离开棱镜,以被光电检测器阵列接收。

    • A diffraction laser encoder apparatus for positional and movement information measurement of a target made with a diffraction grating. The diffraction laser encoder has a laser light source for generating a source beam. A polarization beam splitter assembly comprises a polarization beam splitter for receiving the source beam for splitting a P-polarization component and an S-polarization component of the source beam into parallel and offset beams. A focusing lens focuses the P-polarization component and the S-polarization component beams onto the target diffraction grating and returning diffracted P-polarization and diffracted S-polarization beams back into the polarization beam splitter for generating a detector beam coaxially containing the diffracted P-polarization and the diffracted S-polarization beams. A detector assembly receives the detector beam for electrical processing and analysis for resolving the positional and movement information. In the process, phase information contained in the diffraction signal returned by the target is analyzed.
