Abstract
A multi-aperture passive light sensor and method for detecting motion and edges of an object are described. The sensor may include at least two focusing lenses mounted on a spherical surface for focusing light from the object into the ends of optical fibers, the optical axis for each lens diverging at an angle from that of adjacent lenses depending on the intended application. Each lens is located closer to the end of its associated optical fiber, which is disposed coaxially to the optical axis of the lens, than the natural focal plane of the lens, thereby blurring the light received from the object. Light exiting the fibers is detected by photosensors located at the opposite end of each optical fiber, and voltage differences between the voltages generated in response to the light intensity impinging on the photosensors are used to detect motion and edges of the object.
