SBIR 95-1 SOLICITATION
TURBINE EXHAUST PARTICULATE DETECTION BY LASER-INDUCED INCANDESCENCE
PSI proposes to demonstrate the feasibility of laser-induced
incandescence as a practical, affordable instrument package for
detection of soot particles in test stand gas turbine exhausts.
The basic method utilizes a pulsed laser to radiatively heat
particles, and an imaging detection system to observe spatial
distributions of the time-resolved incandescence from the hot
particles as they cool following cessation of the laser pulse.
Demonstration experiments will observe spatially resolved
incandescence as a function of wavelength and time for various
laser wavelengths and fluences. A key part of the proposed
effort will focus on quantification of the diagnostic for
particle number density and size distribution by comparison to
light scattering and extinction measurements for flame-generated
soot particles. The Phase I effort will also include prototype
design considerations such as ruggedness, component packaging and
cost, and operating characteristics.
Potential Commercial Applications:
The proposed instrument will be useful to the Federal government
and the private sector for all diagnostic and process control
applications requiring the non-intrusive detection of submicron
particulates for environmental, tactical, or operational
purposes. In particular, the device will find applications in
the aviation, transportation, power generation, environmental,
and semiconductor manufacturing industries.
