Effects of Excitation Light Polarization with FrontLight Structure on Lensless Fluorescence Imaging
In this study, we propose to optimize the irradiated light in the front light structure for lensless fluorescence imaging devices by controlling the optical polarization. We fabricated strip diffraction on a thin-cover glass, which operates with a hybrid filter on the image sensor. The control of the excitation light polarization was coupled to diffractor substrates. The results confirm that the effect of $\mathbf{P}$ polarized light can significantly increase the intensity of irradiance light in front of the lensless imaging device, as observed through the contrast of the fluorescent beads.
