Imaging Camera

This paper describes a statistically based efficient algorithm for the laboratory spectral calibration of a low-resolution terrestrial hyperspectral imaging camera operating in the visible range. Didymium oxide is used as a wavelength standard. The observed periodic spatial distortion in the wavelength abscissa of the hypercube is removed automatically through statistical modeling and the calibration of the wavelength abscissa is determined using a numerical method. The performance and cost of this algorithm in removing the spatial distortion are assessed quantitatively.

Discharge Cell

A radio-frequency electrodeless discharge cell for studying the emission spectra of organic molecules is described. This medium pressure source is stable and reproducible with and without sampling it is also self-initiating. Pressure, power, and flow rate studies as well as “gas temperature” measurements were made. Low and medium resolution spectra of aromatic and nonaromatic chlorinated hydrocarbons and chlorinated pesticides are discussed. A qualitative internal wavelength standard is also described.
