Abstract

A method to calibrate the length measurements for digital lensless holographic microscopy is presented. The method estimates the source-to-screen distance of the microscope using the Talbot self-imaging effect. The method’s accuracy is tested using a USAF-1951 target and a monolayer of polystyrene microsphere.
