Abstract:

In the paper On the General Field Illumination in the Focal Plane of A Camera Lens in Daylight, an attempt is made to compute the illumination at the focal plane of a camera lens. With some assumptions made about the distance and power of a source whose image is to be detected, a ratio SB signal-to-background is computed for the specific case in which the focal plane is scanned by a slit which admits a fraction of the total illumination to a photosensitive element. A paper A Comparison of Signal-to-Background Power for Changes in the Number of Slits, in the Number of Detectors, and in the Width and Length of the Slits in a Data Frame extends the SB power ratio, to include the basic design parameters of number of slits, number of detectors, and the dimensions of the slits. A paper Data Reduction for PERSEAS II develops an expression to give the actual azimuth angle in PERSEAS coordinates in terms of the data available from the PERSEAS system. A paper entitled Intensity of Reflected Radiation From a Cone deals with the optical reflection from a conically shaped object. An expression is obtained for the intensity of reflected radiation as a function of range.
