Hemispherical Array Detector for Imaging (HARDI)
Abstract
The Hemispherical Array Detector for Imaging (HARDI) program exploited the benefits of a hemispherical imaging surface. The key concept is that a detector array can be fabricated on a hemispherical substrate using materials such as organic/inorganic semiconductors and that this array can be combined with a single simple lens to produce a wide field of view, small form factor camera that operates over a wide spectral range (400 nm to 1900 nm). Organic materials have been shown to have good electronic and optoelectronic properties including light emission and detection. Furthermore, in-plane organic/inorganic transistors can be incorporated for pre-processing of images. Patterning of these materials on the hemispherical surface has been demonstrated by utilizing maskless laser lithography. This program will transition to DoD systems through a demonstration of an array prototype developed by industrial contractors.
