Aurora optics proposes to develop and demonstrate a fiber-optic fluid flow sensor using the photoelastic effect to directly modulate the amplitude of a beam of light. by mounting a photoelastic pressure sensor on the side of a vortex-swirl flow housing, pressure pulses may be sensed. the pressure… More

The performance and durability of air-breathing engines are sensitive to the environment in which they operate. in the case of turbomachinery operating with particulate-laden air, very serious degradation of engine performance and life can occur. the objective of this program is to evaluate two… More

Modern turboshaft engine control components address such parameters as pressure, temperature, shaft speed, fuel flow, and the position of variable geometry components. however, electronic control components are susceptible to electromagnetic interference, and shielding carries substantial penalties… More

DESCRIPTION: The efficacy and safety of photodynamic therapy (PDT) depends on an understanding of photosensitizer and light biology and dosimetry. Therefore, the ability to accurately determine photosensitizer levels in tumors and at-risk normal tissues is of utmost… More

DESCRIPTION (provided by applicant): Photodynamic therapy (PDT) induces a rapid cellular death used to monitor the effect of the treatment immediately following light delivery. The cellular death causes a reduction in NADH fluorescence, which can provide a reliable probe of whether the tissue has… More
