Abstract

Undesired fringes can appear in interferometric phase measurement, leading to a degradation of contrast and resolution in the retrieved quantitative phase of measured cells and materials. Strong fringes can also introduce significant phase discontinuities, thereby increasing the complexity and time required for phase unwrapping. These fringes often originate from factors such as light reflection between material surfaces of optical devices. Addressing this issue typically necessitates more intricate optical designs or advanced devices, but this comes at the cost of extended design periods and increased expenses. Achieving complete elimination of these fringes may be not always feasible. In this context, we propose an efficient method to mitigate their influences and enhance object contrast and resolution. This method involves modeling the fringes and appropriately determining their frequency support. Primarily based on Fourier filtering, this approach has been successfully demonstrated using real-world interferometric data.
