Widefield Lensless Endoscopy via Speckle Correlations

Not Accessible

Your library or personal account may give you access

Abstract

Recently, researchers from Israel and France have exploited speckle correlations in multicore fibers to perform bend-insensitive, single-shot imaging at various working distances through conventional multicore fibers, without the use of distal optics or wavefront-shaping devices. The lensless technique can image planar objects placed at arbitrary working distances in either reflection or transmission geometry, with the field of view limited by the angular correlation range.
