Laser Diode Schlieren Photography
Laser diodes preferable to conventional lasers or incandescent lamps for Schlieren flow analysis because they are smaller, more rugged, less costly and have lower power requirements.

Gladstone-Dale constant for CF4
The Gladstone-Dale constant, which relates the refractive index to density, was measured for CF4 by counting fringes of a two-beam interferometer, one beam of which passes through a cell containing the test gas. The experimental approach and sources of systematic and imprecision errors are discussed. The constant for CF4 was measured at several wavelengths in the visible region of the spectrum. A value of 0.122 cu cm/g with an uncertainty of plus or minus 0.001 cu cm/g was determined for use in the visible region. A procedure for noting the departure of the gas density from the ideal-gas law is discussed.
