Title: Martin John Richards: Pioneering Innovations in Light Modulation and Laser Dimming Technology

Introduction:

Martin John Richards, an acclaimed inventor based in Gig Harbor, WA (US), has made significant contributions to the field of light modulation and laser dimming technology. With an impressive portfolio of 100 patents and a passion for pushing the boundaries of innovation, Richards has revolutionized the way we experience lighting and visual displays. This article delves into his latest patents and highlights his career journey with notable companies and collaborators.

Spatial Light Modulator for Reduction of Certain Order Light:

One of Martin John Richards' notable inventions is a spatial light modulator (SLM) that effectively separates unwanted reflected light from desired modulated light. The SLM comprises a cover glass, modulation layer, and a collection of pixel mirrors. By strategically positioning the cover glass and the pixel mirrors, Richards introduced a geometrical relationship that distinguishes and filters reflected light, allowing only modulated light to be transmitted. The incorporation of antireflective coatings between optical interfaces further enhances the SLM's efficiency.

Laser Local Dimming for Projectors and Lighting Devices:

Richards also patented an innovative technique called laser local dimming, particularly suitable for projectors and various lighting devices in the cinema, entertainment systems, and display industries. This technique utilizes an array of laser light sources to cover the modulating face of a Digital Micromirror Device (DMD) or other modulators. Each laser light is directed at a lenslet, with overlapping light from neighboring or nearby sources at the modulator. By energizing the lasers at different energy and brightness levels, the light illuminating the modulator can be modulated locally, resulting in precisely controlled dimming. The modulator itself further enhances the modulated light to generate high-quality images.

Career and Collaborations:

Throughout his career, Martin John Richards has actively collaborated with leading companies in the industry. Notably, he has worked with Dolby Laboratories Licensing Corporation and Dolby International AB. Dolby Laboratories, renowned for its breakthrough advancements in sound and visual technologies, provided Richards with an excellent platform to explore and refine his innovative ideas. His collaborations extended to colleagues such as Barret Lippey and Douglas J Gorny, who have also contributed significantly to the advancements in light modulation and laser dimming technologies.

Conclusion:

Martin John Richards' remarkable contributions in the field of light modulation and laser dimming technologies have undeniably transformed the way we perceive and interact with visual displays.
