Time-Resolved Fluorescence Measurements in Real-Time
A prototype instrument that uses fast switching photomultiplier tube (PMT) to acquire real-time time-resolved fluorescence lifetime data has been developed and tested at the University of Arizona. The PMT detector can collect fluorescence data at rates as high as 200 MHz without the production of switching transients. The circuit system also demonstrates...

High Power, Configurable, Pico-Second LED Driver
This technology is a light-emitting diode (LED) driver capable of driving 190mApp of current through an LED. The driver can drive various kinds of LEDs and multiple LEDs in series with up to a total forward voltage of about 8V. The LED is modulated at a single frequency of 200kHz, but future designs could modulate at 1MHz by substituting slower components...

Photo Multiplier System using High Power, Pure Sinusoidal LED Driver with Temperature Stabilization Feedback
This patented technology uses a light emitting diode (LED) to achieve the same imaging results as a laser source, without damaging the tissues. Background: Laser sources are the current standard in fluorescent imaging techniques, but lasers can damage tissue samples over time. This technology is based on a technique used in high energy physics for...
