在爆轰冲击试验中,扫描相机的时间分辩本领一般比分幅相机约高出两个数量级。因此要求精确测量时间信息的试验,均采用扫描相机。但是许多爆轰冲击试验,还要求空间是多维的,而扫描相机一般只能记录空间一维时间信息。过去曾研制了光纤束探针,成功地用于多维空间时间信息的光学测试。但是,它存在一些缺点,探针粗、质量大、
In the detonation impact test, the time resolution of a scanning camera is generally about two orders of magnitude higher than that of a framed camera. Therefore require accurate measurement of time information of the experiment, are using a scanning camera. However, many detonation impact tests also require that the space be multidimensional, whereas scanning cameras typically only record space-time information. Fiber bundle probes were developed in the past and successfully used for optical testing of time information in multidimensional space. However, it has some disadvantages, such as coarse probe, high quality,
