P16551: Observer Calibrator


Project Summary Project Information

An Observer Calibrator (OC) is an instrument designed to measure and distinguish differences in human color perception. The instrument should have a split optical field with two arrays of at least 4 independent LEDs, the capability for an interchangeable optical front end for color stimulus presentation, a robust computer interface for researcher interaction and be designed in such a way that transportation of the instrument is possible. A prototype of the OC was developed by Technicolor in Rennes, France, but currently illumination levels are not high enough and the instrument is not portable.

The goal of this project is to analyze the current prototype and develop a working model of the instrument. By analyzing the existing instrument, the team will be able to identify design changes or requirements that will make the instrument meet each of the given requirements: Brighter, easier to use, somewhat portable, and allow for interchangeable optical presentation. The expected end result is an Observer Calibrator to be used in future RIT color science research. In addition to performing its intended functions, the OC must comply with RIT and FDA regulations and guidelines.
