|Issue Date:||25-Oct-2010||Citation:||Waller, L., Kou, S.S., Sheppard, C.J.R., Barbastathis, G. (2010-10-25). Phase from chromatic aberrations. Optics Express 18 (22) : 22817-22825. ScholarBank@NUS Repository. https://doi.org/10.1364/OE.18.022817||Abstract:||We show that phase objects may be computed accurately from a single color image in a brightfield microscope, with no hardware modification. Our technique uses the chromatic aberration that is inherent to every lens-based imaging system as a phase contrast mechanism. This leads to a simple and inexpensive way of achieving single-shot quantitative phase recovery by a modified Transport of Intensity Equation (TIE) solution, allowing real-time phase imaging in a traditional microscope. © 2010 Optical Society of America.||Source Title:||Optics Express||URI:||http://scholarbank.nus.edu.sg/handle/10635/88031||ISSN:||10944087||DOI:||10.1364/OE.18.022817|
