Hyperspectral Proton Imager

在地球表面，我们受到其磁场的保护，免受太空中许多危险现象的影响 大气层。然而，现代社会的许多方面都依赖于将人或敏感设备放置在 在那里他们可能暴露在破坏性的辐射水平下。自20世纪50年代以来，人们已经意识到 磁场本身导致高能粒子储存在范艾伦辐射带中。其中一些 粒子慢慢泄漏到高层大气中，形成一种非常微弱的蓝色极光，称为“质子极光”。 尽管这些现象已经知道很长时间了，但人们对它们仍然知之甚少，而且仍然是 主要研究工作的目标，例如最近的NASA范艾伦风暴探测器任务。研究极光 从地面，特别是非常微弱的质子极光，尖端的光学仪器是必要的。 Keo Science一直处于开发此类仪器的领先地位，并已为 加拿大在这一高科技设计领域，以及高端成像产品的可行市场。过去几代人 由于敏感、冷却、电荷耦合器件(ccd：类似)的高成本，许多仪器受到了限制 对于大众市场相机中的探测器，但具有高质量和专业特性)。他们通常会 有一个CCD和一组滤光片可以机械地移动到它的前面，以便测量各种 极光的波长。取而代之的是，原型Keo Sentry四象素成像器产生四幅图像 同时，允许更快的操作和真正的高光谱(多色)检测。对…有需求 质子极光成像的研究市场，Keo Quad应该做得很好。阿萨巴斯卡大学 地球空间天文台，在质子极光达到顶峰的非常黑暗的天空下，是做最后决定的理想地方 基奥四合院的发展。我们在2015-2106年黑暗冬夜的测试应该会升级Keo Quad Prototype将成为潜在Keo客户广泛成像应用的最佳选择。

At Earth's surface, we are protected from many dangerous phenomena in space by its magnetic field and atmosphere. However, many aspects of modern society depend on placing humans or sensitive equipment in space where they may be exposed to damaging levels of radiation. It has been realized since the 1950s that the magnetic field itself results in the storage of energetic particles in the Van Allen radiation belts. Some of these particles slowly leak into the upper atmosphere to cause a very faint type of blue aurora called "proton aurora". Despite these phenomena being known of for a long time, they remain poorly understood, and are still the target of major research efforts such as the recent NASA Van Allen Storm Probes mission. To study aurora from the ground, and in particular the very faint proton aurora, cutting edge optical instrumentation is needed. Keo Scientific has been at the leading edge of developing such instrumentation and has established a niche for Canada in this high-tech design area, as well as viable markets for high-end imaging products. Past generations of instruments have been limited by the high cost of sensitive, cooled, charge-coupled devices (CCDs: similar to the detectors in mass market cameras but of high quality and specialized characteristics). They have usually had one CCD and an array of filters to be mechanically moved in front of it in order to measure the various wavelengths of auroal light. The prototype Keo Sentry Quad imager instead produces four images simultaneously, allowing faster operation and true hyperspectral (multiple colour) sensing. There is demand in the research marketplace for imaging of proton auroras, which Keo Quad should do well. Athabasca University Geospace Observatory, under very dark skies where the proton auroras peak, is the ideal place to do final development of the Keo Quad. Our tests during the dark winter nights of 2015-2106 should upgrade the Keo Quad prototype to be the best option for a wide range of imaging applications for potential Keo customers.
