Abstract
An overview of recent developments in time-resolved imaging technology is presented. A directly modulated CCD imaging device has been developed which is suitable for frequency-domain phosphorescence measurements up to more than 400 kHz. This has been used with a recently-developed blue/UV LED source to implement a low-noise, solid-state phosphorescence/fluorescence imaging system suitable for macroscopic and microscopic imaging. For shorter lifetimes a range of new light sources has become available with higher light output and/or higher frequency modulation performance. Acoustooptic tunable filters have also been investigated as optical “light gates” both for modulation of excitation and for time-resolved imaging, and the limits of performance of these devices are discussed.
