ABSTRACT

Optical imaging has till date been the most versatile visualization tool in diverse research areas. Microscopy still remains a diagnostic and a flexible visualization tool, which has been merged with new technologies [1-5]. It has applications spanning from the decoding of the human genome and high-throughput screening to noninvasive imaging of functional and molecular contrast in intact tissues [6,7]. One of the fundamental reasons to
