This paper presents a new type of optical camouflage system based on the retro-reflective projection technology. Retro-reflective projection is a method used to create augmented reality that combines the virtual world with the real world. The conventional model of an optical camouflage system consists of a retro-reflective screen, a projection source and a beam splitter. In such a setup, the user needs to observe an object covered with the retro-reflective screen through a single viewpoint. This is called a monocular system. In our new setup, our aim is to construct a system that has multiple viewpoints by applying a novel projection array system. We will describe the method with which this projection array system is achieved using one projection source, the configuration of the system, and the trade-offs of the system. In addition, we will describe an application of our system in a car. The installed system makes the backseat virtually transparent, allowing the driver to see the blind spots at the rear when reversing the car.
