Multi-Mode Compact Microscopy for High-Contrast and High-Resolution Imaging

We report a multi-mode compact microscope (MCM) for high-contrast and high-resolution imaging. The MCM consists of two LED illuminations, magnification lens, lift stage, housing with image processing control boards. allows multi-modal imaging, including reflection, transmission, higher modes. dual illuminations also provide imaging various targets such as biological samples microcircuits. high dynamic range (HDR) reconstruction increases the acquired images by 1.36 times. microlens array (MLA)-assisted improves resolution through magnified virtual MLA. MLA-assisted successfully provides clear, integrating pinhole mask to prevent overlap without additional alignment. was increased 3.92 times compared that MCM, mode demonstrates 2.46 μm. portable can new platform defect inspection or disease detection on site.
