Abstract

A new design and detection method is proposed of image sensor based LED light marker with pulse modulation using under sampling. We use general image camera to detect different LED light makers with pulse modulation frequency more than 60 Hz. This is according to the under sampling analysis that converts signal with high frequency more than 60 Hz to lower frequency signals using image camera with low frame rate frequency less than 60 Hz. Experimental results are shown with different pulse modulation frequency.
