摘要
针对目前光谱仪器微小型化的几种典型方案在实用化中所存在的几个关键问题 ,提出了一种以固态介质为基底 ,利用固态介质的材料色散及结构尺寸的合理匹配 ,对系统的子午场曲进行补偿 ,以解决光谱探测中谱面平直、光谱线性分布、光线相对探测面为正入射、避免零级谱和负一级谱干扰等一系列问题的光谱仪器微小型化的方案。通过结构与参数的优化设计及计算机模拟显示 ,该方案达到了预期的设计目标。
A novel miniaturized spectrometer with a solid state substrate is presented to solve the key practical problems of several typical micro spectrometers.In the proposed optical system,the meridian field curvature can be compensated by means of mineral dispersion and the optimization design.In this spectrometer,the spectrum plane is perpendicular to the optical axis and the linearly spread spectrum interact with the detector at nearly right angle for optimal detector performance.This configuration also minimizes 0 th and 1 th order interference.Computer simulation has been carried out for design optimization of the optical structure and parameter.The simulation results that the optimized design of this spectrometer meet the anticipated demand.
