High power liquid crystal spatial light modulators
Autor: Donald B. Taber, Bruce K. Winker, Milind Mahajan, Dennis M. Guthals, Dong-Feng Gu, D. Sox, Blair F. Campbell, Bing Wen
Publikováno v: SPIE Proceedings.
A scalable wavefront control approach based upon proven liquid crystal (LC) spatial light modulator (SLM) technology was extended for potential use in high-energy near-infrared laser applications. With use of an ultra-low absorption transparent condu

Description and experimental results of a 58-lb portable LEO satellite tracker
Autor: M. Kozubal, Richard J. Tansey, Andrea Koumvakalis, Blair F. Campbell, R. Dantowitz
Publikováno v: Image Intensifiers and Applications; and Characteristics and Consequences of Space Debris and Near-Earth Objects.
A portable low earth orbit satellite (LEO) tracking mount is described which has dimensions of 21' X 15' X 10' and weighs 58 pounds. Using 22 bit encoders on 9.5' worm gears, an integral microcontroller is capable of adjustable slew rates to six degr

Three-dimensional anisotropic physical optics modeling of three-wave mixing
Autor: Blair F. Campbell, Sam S. Ma, Patrick H. Hu, Dennis M. Guthals
Publikováno v: SPIE Proceedings.
A three-wave mixing crystal is an anisotropic material. To model beam propagation through such a medium, one must have a propagator which includes the anisotropic effects, such as walkoff, in addition to the usual diffraction effect. This requirement

Geminate recombination of CO in rabbit, opossum, and adult hemoglobins
Autor: Blair F. Campbell, Vijay S. Sharma, Douglas Magde
Publikováno v: Journal of Biological Chemistry. 260:2752-2756
The geminate recombination of CO with Hb following dissociation by a 10-ns laser pulse has been studied as a function of pH (9.2 and 7.0 without inositol hexaphosphate and 6.0 with inositol hexaphosphate) and temperature (5-35 degrees C). The hemoglo

Ligand binding channels reflected in the resonance Raman spectra of cryogenically trapped species of myoglobin
Autor: Mark R. Chance, Blair F. Campbell, Joel M. Friedman
Publikováno v: Journal of Biological Chemistry. 262:14885-14890
Variations in the v2 region of the Raman spectra of cryogenically trapped photoproducts of different liganded myoglobins as a function of ligand (CO, O2, and n-butyl isocyanide) and species (whale, tuna, elephant) are reported. These variations are a

Myoglobin recombination at low temperature. Two phases revealed by Fourier transform infrared spectroscopy
Autor: R. Hoover, J. M. Friedman, Mark R. Chance, Blair F. Campbell
Publikováno v: Journal of Biological Chemistry. 262:6959-6961
The low-temperature recombination of CO with myoglobin was studied using Fourier transform infrared spectroscopy. The bound state of carbon monoxide myoglobin has two distinct conformers observed at 1926 and 1945 cm-1 with an intensity ratio of 1 to

Femtosecond Laser Studies Of Distal Side Effects In Myoglobin And Model Compounds
Autor: James C. Marsters, Jean-Louis Martin, Michael J. Mitchell, Blair F. Campbell, Douglas Magde, Kent R. Wilson, Jian Gang Zhu, Charles Dupuy
Publikováno v: SPIE Proceedings.
A colliding-pulse mode-locked ring laser with a four stage Nd:YAG-pumped dye amplifier generates femtosecond pulses at 630 nm with a repetition rate of 10 Hz. Frequency doubling to 315 nm provides photolysis pulses, while continuum generation offers

Linkage of functional and structural heterogeneity in proteins: dynamic hole burning in carboxymyoglobin
Autor: Blair F. Campbell, Joel M. Friedman, Mark R. Chance
Publikováno v: Science (New York, N.Y.). 238(4825)
Inhomogeneous broadening of the 760-nanometer photoproduct band of carboxymyoglobin at cryogenic temperatures has been demonstrated with a dynamic hole burning technique. Line-shape changes and frequency shifts in this spectral band are generated by
