为了推进大气折射的理论研究，低仰角观测到的大气折射仍然值得分析和探索。在一些工程应用中，有时必须观测天顶距较大的物体。开展低仰角大气折射观测研究具有重要意义。然而，人们认为在较低仰角下测量大气折射很困难。提出了利用双视场差分测量确定大气折射的新思路。参考HIPPARCOS卫星的观测原理，研制了双视场样机。 2013年8月，进行了实验观测，通过样机获得了较低仰角的大气折射。天顶距78.8°处大气折射测量值为240.23″±0.27″，验证了双视场大气折射差分测量的可行性。指出原型机的光照收集能力不足、气象数据记录不准确、观测和数据处理自动化程度较低等局限性，需要在后续工作中加以改进。
For the sake of advancing theoretical research about atmospheric refraction, the atmospheric refraction observed at lower angles of elevation is still worth analyzing and exploring. In some engineering applications, objects with a larger zenith distance must sometimes be observed. Carrying out observational research on atmospheric refraction at lower angles of elevation has an important significance. However, it has been considered difficult to measure the atmospheric refraction at lower angles of elevation. A new idea for determining atmospheric refraction by utilizing differential measurement with double fields of view is proposed. Taking the observational principle used by the HIPPARCOS satellite as a reference, a prototype with double fields of view was developed. In August 2013, experimental observations were carried out and atmospheric refractions at lower angles of elevation were obtained by the prototype. The measured value of atmospheric refraction at a zenith distance of 78.8° was 240.23″ ± 0.27″, and the feasibility of differential measurement of atmospheric refraction with double fields of view was verified. Limitations of the prototype, such as inadequate ability to gather light, lack of accurate meteorological data recording, and a low level of automation in observation and data processing, are pointed out, which need to be improved in subsequent work.
