Abstract
Complementary metal oxide semiconductor (CMOS) cameras that can measure the phase and amplitude of periodically modulated optical signals have been developed. These allow parallel lock-in imaging at up to 256 x 256 pixels resolution without the need for slow and costly mechanical scanning. In conjunction with a differential surface plasmon resonance (dSPR) system, spatially resolved SPR imaging has been achieved with sensitivities of better than 10 microRIU per pixel per second. Results demonstrating the performance of modulated light cameras for dSPR imaging and high resolution SPR microscopy are presented and discussed.
