Abstract
Imaging interferometric microscopy (IIM) is an optical microscopy resolution enhancement technique involving combining multiple sub-images to increase resolution. Several image reconstruction challenges can degrade the image quality including the frequency, phase deviations between sub-images, and maintenance of a uniform frequency response across the entire space. This work proposes methods to address these issues. The methods are first compared in simulation using a Manhattan structure of 260-nm critical dimension with 2-µm-pitch calibration grating on the sides. The proposed correction methods are then applied to the experimental results and found to be effective in improving the image quality of IIM.
