N2 - It is a great challenge to use visible and coherent light source to realize high-fidelity optical transmission in free space around the corner where blockade, reflection and scattering occur, and quality of the information retrieved at the receiving end is significantly affected. In this Letter, we propose a novel method to solve the problems encountered in data transmission in free space around the corner when visible and coherent light source is applied. The proposed method is highly robust to coherent light diffraction, multiple scattering effect and environmental noise, which can make it promising for practical applications. A number of optical experiments have been conducted to successfully transmit different types of signals (e.g., analog) in free space around the corner to achieve high fidelity. The proposed method could lead to a development in many relevant applications, e.g., optical transmission in free space, information propagation in free space, telecommunication, and optical security.
