We propose a new layout for the Offner imaging hyperspectrometer that is utilized onboard small space vehicles. The layout is based on a method of adjusting the adaptive temperature-dependent optical scheme by moving just two coaxial optical components located inside the hyperspectrometer. We present the results of modeling for a temperature range of -40 to +45 °C and an optical experiment using a heat and cold chamber for the range of 12 to 40 °C, proving the basic functionality of the proposed layout. Based on simulation results, the new layout is supposed to allow the hyperspectrometer to operate in a temperature range of -40 to +45 °C without its optical characteristics deteriorating, thus making it suitable for work onboard space or stratospheric vehicles.
我们提出了一种用于小型航天器上的奥弗纳成像高光谱仪的新布局。该布局基于一种通过移动仅位于高光谱仪内部的两个同轴光学组件来调整与温度相关的自适应光学方案的方法。我们给出了在 -40 至 +45 °C 温度范围内的建模结果，以及在 12 至 40 °C 范围内使用热冷室进行的光学实验结果，证明了所提出布局的基本功能。基于模拟结果，新布局应能使高光谱仪在 -40 至 +45 °C 的温度范围内运行而不使其光学特性变差，从而使其适用于在太空或平流层飞行器上工作。
