掩星观测系统的时间戳
Verifying timestamps of occultation observation systems
摘要：
我们描述了一个图像时间戳验证系统，以确定曝光定时特性和连续性的图像成像相机和记录器，参考协调世界时（UTC）。最初的用途是验证恒星掩星记录系统的时间戳，但该系统适用于月球闪光，行星凌日，精灵记录或任何需要可靠时间戳的领域。该系统提供良好的时间分辨率（低至2毫秒，参考UTC），并提供曝光持续时间和帧间死区时间信息。该系统使用廉价的现成组件，需要最少的组装，并且不需要高压组件或连接。我们还描述了一个应用程序来加载FITS（和其他格式）的图像文件，它可以解码验证图像的时间戳。提供源代码、接线图和内置应用程序，以帮助构建和使用器械。
英文摘要：
We describe an image timestamp verification system to determine the exposure timing characteristics and continuity of images made by an imaging camera and recorder, with reference to Coordinated Universal Time (UTC). The original use was to verify the timestamps of stellar occultation recording systems, but the system is applicable to lunar flashes, planetary transits, sprite recording, or any area where reliable timestamps are required. The system offers good temporal resolution (down to 2 msec, referred to UTC) and provides exposure duration and interframe dead time information. The system uses inexpensive, off-the- shelf components, requires minimal assembly and requires no high-voltage components or connections. We also describe an application to load FITS (and other format) image files, which can decode the verification image timestamp. Source code, wiring diagrams and built applications are provided to aid the construction and use of the device.
