ICCDcamera based Luminescence Lifetime Imaging

Abstract

We have developed an ICCDcamera based luminescence lifetime imaging system, it enables the imaging of luminescence lifetime of pressure sensitive paint. This system consists of an illuminator for excitation, an ICCDcamera for imaging, a timing controller and a computer for image acquisition and processing. Basic characteristics of this system and its application to the gated intensity ratio method are described. PSPs measured here are PtOEP and FtTFPP. In the measurement by the gated intensity ratio method, both pulsed excitation light and sine-wave excitation light have been applied. With the single-exponential approximation in image processing, the obtained lifetime value is roughly in agreement with the value measured by conventional lifetime method.
