Title: **Joseph F. Arnold: A Pioneer in Print Scanner Illumination Technology**

Introduction

Joseph F. Arnold, an innovative inventor based in Palm Beach Gardens, FL, has made significant contributions to the world of print scanning technology. With a impressive portfolio of three patents, Arnold is recognized for his groundbreaking work in developing systems and methods for illuminating platens in print scanners. His inventions not only enhance image quality but also improve the efficiency of the scanning process.

Latest Patents

Arnold's latest patent focuses on the development of hybrid illumination systems that utilize both diffusion and collimation techniques to provide flat, uniform light at a platen. This innovative system incorporates one or more diffusers positioned between the illumination source array and a collimating lens. By doing so, it employs diffused light to illuminate the platen in a print scanner effectively.

The illumination system is particularly noteworthy for its use of a light wedge, which reflects light internally, enhancing the diffusion of light. The patent further specifies that the illumination source array is designed to emit blue/green light, with a wavelength approximately equal to 510 nm. The sources are segmented into a center region and a perimeter region, with a higher density of sources in the perimeter to counteract natural light falloff, enabling remarkable intensity control options that can be executed individually or in groups.
