ENGINEERING RESEARCH EQUIPMENT: A Thermographic-Phosphor Fluorescence Imaging System for Rapid Transient and Microscopic Studies

该提案是对REG计划公告的回应，并请求支持购买一个高速、高分辨率的视频系统，由几名调查人员共享。该系统的主要用途是同时测量具有快速瞬变的微尺度环境中的温度和热传递。利用稀土掺杂热成像荧光粉的激光诱导荧光，已经开发出一种新的成像技术，能够测量0-250℃的温度，空间分辨率为10微米，精度为0.5℃。拟议的系统具有12,000帧/秒的速率和机载DRAM存储，升级后的系统将能够测量高度不稳定的现象，并可大大促进对这些流动的理解。

The proposal was submitted in response to the REG Program Announcement and requested support to purchase a high speed, high resolution video system to be shared by several investigators. The primary use of this system would be for the simultaneous measurement of temperature and heat transfer in microscale environments with rapid transients. Utilizing laser induced fluorescence of rare earth doped thermographic phosphors, a novel imaging technique has already been developed that is capable of measuring temperatures from 0 to 250 C with 10 micron spatial resolution and 0.5 C accuracy. With the acquisition of the proposed system, which has a rate of 12,000 frame/sec and on board DRAM storage, the upgraded system would permit the measurements of highly unsteady phenomena and could significantly advance the understanding of these flows.
