Instrumentation Development - Novel Demodulation Techniques (Single-Point and 2-D) for Picosecond Laser-Based Combustion Diagnostics

摘要：Linne CTS- 9711889这是一个基于锁模钛蓝宝石激光器的皮秒泵浦/探针仪器的仪器开发项目。增加一个再生放大器，可以观察高速反应流场中关键物质的绝对浓度，也许不受压力的影响。这项工作还包括设计新型解调传感器，该传感器可广泛应用于多种应用，如组织弹道成像、成像光谱仪和夜视设备。

Abstract- Linne CTS- 9711889 This is an instrumentation development project on a picosecond pump/probe instrument based on mode-locked Ti: sapphire lasers. Addition of a regenerative amplifier makes it possible to observe absolute concentrations of key species in reacting flow-fields at high speeds and perhaps independent of pressure. The effort also includes design of novel demodulation sensors that could have broad applicability in such diverse applications as ballistic imaging in tissue, imaging spectrographs, and night-vision devices.
