Heuristic optimization in penumbral image for high resolution reconstructed image.
- Published 2010 in The Review of scientific instruments
Abstract
Penumbral imaging is a technique which uses the fact that spatial information can be recovered from the shadow or penumbra that an unknown source casts through a simple large circular aperture. The size of the penumbral image on the detector can be mathematically determined as its aperture size, object size, and magnification. Conventional reconstruction… (More)
