A new autofocus method based on angular spectrum method in digital holography
The determination of numerical reconstruction distance is key to recover the wavefront at focal plane in digital holography. In this paper, we propose a new autofocus method based on angular spectrum method (ASM). The ...
A new phase error compensation method in digital holographic microscopy
In this paper we present a new method to compensate for phase aberrations and image distortion with recording single digital hologram in digital holographic microscopy. In our method, tilt is removed from the abberrated ...
Digital off-axis holography with angular multiplexing and synthetic aperture
This paper discusses conventional synthetic-aperture method combined angular multiplexing in digital holography to increase the resolution and to enlarge the field of view at the same time. A structured illumination is ...
Phase errors elimination in compact digital holoscope (CDH) based on a reasonable mathematical model
In the compact digital holoscope (CDH) measurement process, theoretically, we need to ensure the distances between the reference wave and object wave to the hologram plane exactly match. However, it is not easy to realize ...
