Customer Handoff & Final Project Documentation

Team Vision for Final Demo and Handoff
This page holds the final documentation for the observer calibrator. Below is our customer, Dr. Fairchild, with the Observer Calibrator during the final handoff.
Test Results Summary
The two images below show spectral power graphs of each of the LED sets. Both the original, unmixed colors and some mixed colors are shown, where the mixed colors are created by the combination of various LED primaries.
The final OC, with one integrating sphere removed for demonstration, can be seen below.
The stability of the luminance over time was measured by taking several measurements of luminance. The results are shown below.
Risk and Problem Tracking
Our risk assessment document tracks risks we identified during the beginning of MSD and is continually updated as the likelihood of risks changes and as more risks are identified. Nearly all the risks are driven to zero at this point. Our customer has stated that the LEDs are bright enough, and was impressed with the final result. The user interface was simple enough, and the researcher interface remains fully customizable through MATLAB. The only remaining risk is in dropping or damaging the OC through transport. Though the system is robust, this always remains a risk for the product.
Our problem tracking document lists issues that have arisen during the design of the Observer Calibrator, marks our solutions to these issues, and identifies the path to ensuring the problem is solved. No issues arose during this phase, so the status is unchanged; all problems have been solved.
Final Project Documentation
Our final technical paper was submitted to the 29th Annual Electronic Imaging Symposium. The paper can be found here.
Our poster hangs in the hall of the Program of Color Science, and can be seen here.
Our final Bill of Materials can be found here.
Documentation for using and maintaining the Observer Calibrator is provided here.
In the paper, we recommend the following for future work efforts:
- Different LED selection for more control over spectral power
- The use of better reflective paint in the integrating spheres to improve reflectance at shorter wavelengths
