Description: calculate the band of Fabry-Parot Filter -A Fabry-Parot Filter consist of the cavity formed by two highly reflective mirrors placed parallel to each other , as shown in the figure 1.The input light beam to the filter enters the first mirror at right angles to its surface. The output of the filter is the light beam leaving the second mirror. This filter is called Fabry-Parot or etalon. This is a classical device that has been used widely in interferometric applications. Fabry-Parot filters have been used for WDM in several optical network test beds. There are better filters today, such as thin film resonant multi cavity filter and they can still be viewed as Fabry-Perot filter. This type of filter transmits a narrow band of wavelengths and rejects wavelengths outside of that band. An interesting feature of this type of filter is its ability to "select" a different peak wavelength as the filter is tilted Platform: |

Description: 本文介绍了用来测量对流层温度垂直分布的基于高光谱分辨率雷达技术的瑞利-米激光雷达系统（激光是对人眼安全的355nm波长的紫外线）。在该系统中，用两个法布里-珀罗标准具滤波器对影响大气温度的两个瑞利信号进行过滤。这些滤波器放在瑞利散射频谱的同一侧，并带有双端口光学输出通道。这种配置对米氏散射能获得较高的抑制比以及合理的瑞利散射透光率。米氏信号用第三个位于激光频率中间位置的法布里-珀罗标准具滤波器进行检测。这三个滤波器的参数是经过数值计算优化了的。实验结果表明，对于这两个瑞利通道都能实现-45dB的米散射抑制和大于1 的瑞利透光率。文中还介绍了一种用于校正气溶胶散射实验中所测得的温度（受到气溶胶和云的影响）的方法。初步试验和仿真证明，该设备中的双通道标准具和米散射校正在实际应用中有较高的性能。-A Rayleigh–Mie-scattering lidar system at an eye-safe 355nm ultraviolet wavelength that is based on a
high-spectral-resolution lidar technique is demonstrated for measuring the vertical temperature profile
of the troposphere. Two Rayleigh signals, which determine the atmospheric temperature, are filtered
with two Fabry–Perot etalon filters. The filters are located on the same side of the wings of the Rayleighscattering
spectrum and are optically constructed with a dual-pass optical layout. This configuration
achieves a high rejection rate for Mie scattering and reasonable transmission for Rayleigh scattering. The
Mie signal is detected with a third Fabry–Perot etalon filter, which is centered at the laser frequency. The
filter parameters were optimized by numerical calculation。 Platform: |
