Abstract :
A novel distance mapping camera, the divergence-ratio axi-vision camera (Divcam), is proposed. The decay rate of the illuminating light with distance due to the divergence of the light is used as a means of mapping the distance. Resolutions of 10 mm over a range of meters and 0.5 mm over a range of decimeters were achieved. Special features of this camera are its high resolution, real time operation, simplicity, compactness, light weight, portability, and yet low fabrication cost.
