The 2D-S (Stereo) Probe: Design and Preliminary Tests of a New Airborne, High-Speed, High-Resolution Particle Imaging Probe

Autor: Darren O’Connor, Qixu Mo, Patrick Zmarzly, Haflidi Jonsson, B. Baker, R. Paul Lawson, Kim Weaver

Publikováno v: Journal of Atmospheric and Oceanic Technology. 23:1462-1477

The design, laboratory calibrations, and flight tests of a new optical imaging instrument, the two-dimensional stereo (2D-S) probe, are presented. Two orthogonal laser beams cross in the middle of the sample volume. Custom, high-speed, 128-photodiode

In early February 2001 (during the austral summer), over 900 000 digital images of ice crystals were recorded at the South Pole using two ground-based cloud particle imagers (CPIs). Of these, 721 572 crystals >50 μm were classified into crystal habi

Characterization of Aerosol Inlets and Ducts

Autor: R. P. Lawson, Patrick Zmarzly

During the first thirty days of the Phase I project, preliminary calculations were performed to determine the effect of inserting windows into the FSSP sample volume. Based on a first order approximation, the windows will displace the FSSP sample vol

In-situ ammonia analyzer for process control and environmental monitoring

Autor: K. W. Groff, Fritz Bien, Jamine Lee, Joel A. Brand, Garth Monlux, Patrick Zmarzly, Gregory J. Fetzer, M. Walker, Neil Goldstein, Steven Richtsmeier

Publikováno v: Advanced Technologies for Environmental Monitoring and Remediation.

An ammonia monitor designed for in situ smoke stack or exhaust duct applications is discussed here. A probe composed of a diffusion cell with a protected multipass optical measurement cavity provides the optical interaction with the sample. Other com

Tunable diode laser absorption spectroscopy of common combustion gases at elevated temperatures

Autor: Gregory J. Fetzer, K. W. Groff, Garth Monlux, Joel A. Brand, Patrick Zmarzly

Publikováno v: SPIE Proceedings.

Tunable diode laser absorption spectroscopy (TDLAS) shows promise for a number of environmental monitoring applications. This technique is advantageous over more classical methods because of excellent dynamic range, signal to noise ratios, and narrow
