Abstract
In this paper, we propose the use of electrically-addressable
lens devices for performing fast non-mechanical axial scanning when
imaging three-dimensional samples. This non-mechanical method can
be implemented in any commercial microscope. The approach is based
on the insertion of the tunable lens at the aperture stop of the microscope
objective. By tuning the voltage, a stack of depth images of 3D specimens
can be captured in real time and with constant magnification and resolution.
The main advantage of our technique is the possibility of performing
fast axial scanning free of mechanical vibrations.
