Title: Randal B Chinnock: A Pioneer in Illumination and Ocular Surface Interferometry

Introduction:

Randal B Chinnock, based in Southbridge, MA, is a prolific inventor with an impressive portfolio of 35 patents. His expertise lies in the field of illumination technologies and ocular surface interferometry. Through his groundbreaking inventions, Chinnock has contributed significantly to the advancement of imaging and illumination methods in various industries. This article explores some of his notable patents, the companies he worked for, and his collaborations with esteemed colleagues.

Innovations and Patents:

1. Method and apparatus for illuminating an object field imaged by an image sensor:

One of Chinnock's recent patents introduces an innovative illuminator apparatus and method for illuminating an object field imaged by a rectangular image sensor. This technology utilizes an optical fiber that transmits light beams with varying spectral properties to an integrating element. The integrating element then combines the light beams to produce a uniform illumination beam, which is projected onto the object field by an illumination projector. This invention enables the creation of a rectangular illuminated region that aligns with the portion of the object field captured by the rectangular image sensor.

2. Ocular surface interferometry (OSI) for imaging, processing, and/or displaying an ocular tear film:

Chinnock's expertise also extends to ocular surface interferometry. His patented devices, systems, and methods employ imaging techniques focused on the lipid layer of the ocular tear film. By capturing interference interactions and utilizing multi-wavelength light sources, this technology enables the measurement of tear film thickness. Through the subtraction of background signals, accurate and detailed images of the tear film can be obtained, facilitating the diagnosis and treatment of ocular surface conditions.
