Luminescence lifetime imaging using a cellphone camera with an electronic rolling shutter

Luminescence lifetime imaging systems are typically complex and expensive instruments targeting bench-top applications. We present a low-cost approach for video frame rate luminescence lifetime imaging on the microsecond scale based on a cellphone camera. The luminescence lifetime is mapped by measuring the phase shift of optical fringes captured by a camera with an electronic rolling shutter at 30 frames per second. Luminescence lifetime …
