Stripe-shaped apertures in confocal microscopy

Not Accessible

Your library or personal account may give you access

Abstract

We have theoretically verified that, compared with the aperture shapes of previous research, combining two stripe-shaped apertures in a confocal microscope with a finite-sized pinhole improves the axial resolution to a certain extent. Because different stripe shapes cause different effects, we also investigated the relationships among resolution, shapes, pinhole size, and the signal-to-background ratio.
