The optical imaging and radiometric properties of arrays of GRIN fiber lenses (Selfoc lens arrays) have been studied as a function of the length of the fibers. Experiments measured the object-to-image distance, image quality (MTF), depth of focus, im

In a raster scanning printer, a laser beam is scanned across a photoreceptor in a direction perpendicular to the photoreceptor motion. When there is vibratory motion of the photoreceptor or wobble in the polygon mirror, the raster lines on the photor

The imaging and radiometric properties of erect lens arrays made up of small biconvex microlenses are derived from a ray analysis. The lens arrays provide erect, unit magnification images. The relationship between the radii of curvature, the lens thi

A theoretical treatment of the electrical behavior of pulsed discharges in gas‐filled flashlamps is presented. The theory is based on a simple model of the plasma and a balance of electrical power input and radiation output. It is assumed that the

The effect of superradiance in the decay of coupled harmonic oscillators has been demonstrated in some simple experiments with two tuning forks and resonators. The results show the theoretically predicted shortening and lengthening of the decay times

Gradient-index lens arrays that make reduced or enlarged images have been invented at Xerox Corp. An important optical property of these lens arrays is their radiometric speed. Thus a general procedure for the radiometric analysis of arbitrary magnif

A novel concept of a gradient-index lens array for reduction and enlargement is described. The array is composed of radial gradient-index rod lenses arrayed in a fanlike manner. Design and radiometric equations are presented. Some image aberrations a

Some radiometric properties of gradient-index fiber lenses and lens arrays are explored. Consideration is restricted to the paraxial region of fibers that produce erect images at unit magnification. In two instances the radiometric properties of thes

A simple theoretical model of visible light emission from xenon flashlamps is presented. The continuum light emission is calculated from the rate of electron-ion recombination in the xenon plasma, which is treated as a greybody in thermal equilibrium
