Test and Measurement World published an interview with SiOnyx test engineer. Not much interesting stuff there, other than performing tests with a "monochrometer" and an unusual explanation of blooming:
"I use my background in physics and fiber optics to suggest tests to the designers. For example, I may recommend testing using both pulsed and continuous light. Using pulsed light lets you see how long a device takes to respond. This kind of testing is important for sensors, because of possible "blooming." That is, if the response is too slow, residual signal from a sensor's response will add to that of the next sample, producing an error."
