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宝石激光器的皮秒泵浦/探测仪器的仪器开发项目。 再生放大器的加入使得有可能观察到的绝对浓度的关键物种在反应流场在高速和可能独立的压力。 这项工作还包括设计新型解调传感器，这些传感器可以在组织中的弹道成像，成像光谱仪和夜视设备等各种应用中具有广泛的适用性。

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.
