Abstract

We present a novel method for estimating 3-D positions of near light sources by using highlights on the outside and inside of a single clear hollow sphere. Conventionally, the positions of near light sources have been estimated by using observed highlights on multiple reference objects, e.g. mirror balls., ICPR 2012 : 21th International Conference on Pattern Recognition , Nov 11-15, 2012 , Tsukuba, Japan

Abstract

New developments in fluorophores as well as in detection methods have fueled the rapid growth of optical imaging in the life sciences. Commercial widefield microscopes generally use arc lamps, excitation/emission filters and shutters for fluorescence imaging. These components can be expensive, difficult to maintain and preclude stable illumination. Here, we describe methods to construct inexpensive and easy-to-use light sources for optical microscopy using light-emitting diodes (LEDs). We also provide examples of its applicability to biological fluorescence imaging. [ABSTRACT FROM AUTHOR]
