Abstract

In this paper, we investigate the defocused image in optical camera communications and the use three parameters including half power full width, maximum intensity, and slopes of the hazy area to characterize the blurred image. The paper outlines theoretical analysis for the blurry image using the captured image of the light source and the circle of confusion. An experimental test bed is developed to investigate the effect of width, height and slopes of the image of defocusing of the camera. Results show that for a larger aperture, which results in higher received power, the interference level between two light sources is increased due to defocusing of the camera.
