Outline of Final Research Achievements |
We propose a three-dimensional microscope imaging system for tuning a focal plane in a depth direction by using a composite objective lens with a liquid crystal (LC) lens without any mechanical movements. The focal length of the microscope imaging system is controlled by applying the voltage to electrodes of the LC lens with circularly hole-patterned electrode and external flat transparent electrode. The captured image of each focal length in the depth direction can be taken by using CMOS camera and ring a light emitting diode (LED) illuminator. The sharp and clear distributions can be derived by automatically selecting the images without highly reflective brightness. The all-focused images and depth mapping properties of the microscopic objects are obtained by processing our proposed image digital filter from contentious focal images.
