Abstract
We demonstrate the use of novel visible and infrared light-sensitive optoelectronic fiber in the development of large scale photodector arrays. Unlike conventional point photodetectors these one-dimensional linear photodectors are capable of sensing light along the entire length of the fiber and 360 radially. Multiple fibers can be arranged in an orthogonal grid to create a two-dimensional fiber web. The fiber web is capable of tracking a time-and space-varying beam, and output it onto a computer screen. Other imaging applications for the fiber web include image recovery for 2D images based on Computed Axial Tomography concepts. and lensless imaging. Lensless imaging is accomplished d using two fiber webs separated by a fixed distance, recovering the intensity distribution on each fiber web, and applying a phase retrieval algorithm to the two distributions. Furthermore, fiber webs consisting of six planar arrays forming a cube can be used to detect incident light in three dimensions.
