Title: Colin Shaw McArthur: Innovator in Optical Laser Technology

Introduction

Colin Shaw McArthur is a notable inventor based in Winston-Salem, NC (US). He has made significant contributions to the field of optical laser technology, particularly in the area of perforation systems for paper products.

Latest Patents

McArthur holds a patent for a "Rotary beam chopper and scanning system." This invention involves an optical laser beam chopper designed to convert a continuous beam into a series of scanning impulses. The system is particularly useful for perforating a moving web, such as the thin paper used in producing cigarette filters. The technology utilizes a coherent light source that produces a beam, which passes through a rotary chopper system. This system incorporates multiple rotary discs, each carrying annular rings divided into segments. Selected segments are made of reflective material, acting as mirrors for the laser beam, while others are apertures that allow the beam to pass through. By aligning the apertures and reflective surfaces, the rotation of the discs directs the beam along various paths, creating spaced perforations in the web.
