Our PhD student, Miss Zilan Pan, obtained the Third Prize of the Best Student Presentation Award in the International Conference on Optical and Photonic Engineering (icOpen) 2022 for the paper “Optical Transmission through Thick Biological Tissue using Optical Modulation”. Accurate data transmission is important in biological applications and biomedical devices. Realizing high-fidelity optical wireless transmission with a large penetration depth is desirable. Here, a sequence of amplitude-only patterns at the transmitter is considered as information carrier to encode the transmitted data. The total light intensity at the receiving end is collected and recorded by a bucket detector. Miss Pan’s research work verifies feasibility and effectiveness of the proposed approach with different thicknesses of a biological sample. The experimental results demonstrate the proposed method based on zero-frequency modulation using low light intensity.
