【摘要】 本文以紫金山天文台太阳光谱仪为例,估算大型天文分光仪器的分光流量,同时建立了一套实验性的雷迪康(Reticon)系统以测量该光谱仪的实际流量。测得的和估算的结果间的一致性,除个别波长外,堪称满意。这种估算对设计固体检测器系统提供了极为有用的定量依据。更多还原

【Abstract】 Taking the solar spectrograph of Purple Mountain Observatory for example, this paper describes a method to estimate the spectral fluxes of large astronomical spectroscopic instruments. Meanwhile an experimental Reticon system has been installed for measuring the real fluxes of our spectrograph. The consistence between the measured fluxes and the estimated ones seems satisfactory with the exception of one wavelength, indicating the correctness of our method. This estimation provides a quantitative basis which is very useful for the design of solid-state detector systems.更多还原
