Abstract

The accuracy of cinematic analysis with camera system depends on frame rate of used camera. Specific case of cinematic analysis is in medical research focusing on microscopic objects moving with high frequencies (cilia of respiratory epithelium). Higher frame rate of camera (400 fps e.g.) causes that exposure time for imaging sensor is too short, so it is necessary to use lightning source with higher optical (illuminating) efficiency and higher reliability. Paper focuses on design of LED illumination modules, their control and supplying circuits for high speed imaging purposes.
