This paper presents a novel conformal thermal monitoring sheet (TMS) sensor array with differential thermal sensitivity for measuring temperature distributions over large surface areas. Performance of the sensor array is evaluated in terms of thermal

A compact laser-produced plasma X-ray source that radiates 1 nm X-rays with an average power of 24 W in 2π steradians is presented. The X-ray conversion efficiency is 9% of the laser power delivered on target. The 300 W laser power is generated by a

Ultra small magnetic field sensors are created using magneto-optic slab waveguides coupled to optical fiber. The magneto-optic material used is bismuth-doped rare earth iron garnet (Bi:RIG). By etching close to the core of D-type optical fiber and at

We have used laser-induced fluorescence (LIF) to monitor the charge-exchange ion erosion of the molybdenum accelerator electrode in ion thrusters. This real-time, nonintrusive method was implemented by operating a 30cm-diam ring-cusp thruster using x

An approximate analytical model has been developed which allows the voltage characteristics of the liquid crystal layer of a silicon liquid crystal light valve to be determined once the photocurrent level and device parameters have been specified. Th

An optical technique for measuring the sputtering rate of a molybdenum surface immersed in a xenon plasma has been developed and demonstrated. This approach, which may be useful in real-time wear diagnostics for ion thrusters, relies on laser-induced

We have constructed and demonstrated a single-pixel implementation of an all-optical membrane-based spatial light modulator as a compact optical wave-front error correction device. High rates of response of as much as 20 kHz in an open-loop configura

We have demonstrated an all-optical diagnostic system that enhances the observation of defects in periodic structures. This real-time technique employs a spatial light modulator as a smart-pixel array for information processing in the Fourier transfo

Self-pumped optical phase conjugation has been demonstrated for the first time to our knowledge in a resonant atomic system. This process was implemented by using a single cw pump beam to excite a sodium-vapor oscillator. The counterpropagating optic
