Abstract

The condenser is one of the most important components in many transmitted light compound microscopes. In this Letter, was shown that such a condenser can be replaced by a solution of liquid crystal in a polymer matrix (PDLC) and back light lamp to achieve greater imaging flexibility and functionality. By changing the voltage applying to the PDLC, we change the amplitude ratio of the non-scattered and the singly forward scattered interfering components significantly affects the spatial-frequency filtering by PDLC. Without mechanically scanning the sample or changing the microscope setup, the proposed approach can be used for dark-field imaging, bright-field imaging, microscopy sectioning, and digital refocusing. Images of a starfish embryo were acquired by using such an approach for demonstration.
