Abstract

The compound eye of the insect in its simplest concept creates an image from the environment over a solid angle, yet in practice angular resolution varies significantly across most compound eyes. We have examined the case of linear optical (paraxial) arrays in which optical axes are parallel. We demonstrate that a paraxial array directly measures the speed of translation orthogonal to the optical axes, while when rotated, it detects range as a ratio of optical flow and angular velocity. A series of experiments was conducted to demonstrate the viability of the device.
