Research output: Contribution to journalConference articlepeer-review


Lateral resolution enhancement in confocal self-interference microscopy (CSIM) is evaluated. CSIM, which uses the birefringence of the calcite plate to generate self-interference pattern, sharpens the central lobe of the effective spot. Numerical simulation results of two-dimensional imaging performances are presented. Two-point resolution of 149nm is achieved, which is enhanced by nearly 100% compared to that of confocal microscopy.
