Journal ArticleDOI

Restoration of images captured by a staggered time delay and integration camera in the presence of mechanical vibrations.

TL;DR: Analysis and restoration of images acquired by thermal staggered TDI sensors in the presence of mechanical vibrations that may cause space-variant image distortions are studied.
Journal ArticleDOI

Spatial-frequency- and wavelength-dependent effects of aerosols on the atmospheric modulation transfer function.

TL;DR: In this article, experiments carried out over diagonal lines of sight through the entire atmosphere support the concept of spatial-coherence degradation through forward scattering as described by an aerosol modulation transfer function that strongly affects the wavelength dependence of imaging through the atmosphere.
Journal ArticleDOI

Simple Mathematical Models for Temporal, Spatial, Angular, and Attenuation Characteristics of Light Propagating Through the Atmosphere for Space Optical Communication:: Monte Carlo Simulations

TL;DR: In this paper, the authors developed a mathematical model to characterize propagation through a turbid medium at three different wavelengths in the visible and near infrared spectral range, based on relations between the temporal, angular, and spatial spread of electromagnetic unpolarized radiation, geometrical path length, particle size distribution, and the medium's propagation parameters such as Mie scattering, and absorption coefficients, Mie phase-function, and optical thickness.
Journal ArticleDOI

Abnormal glow discharge detection of visible radiation.

TL;DR: Extension of abnormal glow discharge detection of electromagnetic radiation to visible wavelengths is observed with inexpensive commercial indicator lamps and spectral response and mechanisms of detection are discussed and advantages over gas-filled photodiodes noted.
Journal ArticleDOI

Subnormal Glow Discharge Detection of Optical and Microwave Radiation

TL;DR: In this paper, the relationship between glow discharge detector physical and electronic parameters is discussed in terms of physical electronics and an equivalent circuit and a comparison of abnormal and subnormal glow mode properties is made.
