Quantitative phase imaging verification in large field-of-view lensless holographic microscopy via two-photon 3D printing. [PDF]

open access: yesSci Rep
Large field-of-view (FOV) microscopic imaging with high lateral resolution (1-2 microns for high space-bandwidth product) plays a pivotal role in biomedicine and biophotonics, especially within the label-free regime, e.g., for whole slide tissue quantitative analysis and live cell culture imaging.

Rainbow holographic interferometry [PDF]

open access: yesOptics Communications, 1978
Abstract A one-step rainbow holographic process is applied to holographic interferometry. Experimental demonstrations of double exposure and time-average interferograms are included. Comparison is made with the conventional holographic process. We found that the rainbow process provides better equality and less speckle noise.
