Abstract
High resolution is important properties of the compact microscopy in the point-of-care testing (POCT) and management of various infectious diseases. However, the current high-resolution compact microscopy usually has complicated algorithm at the expense of real-time. This letter experimentally demonstrated a method to improve the resolution of compact microscope by employing the microsphere, in combination with the tube lens placed on the small-end of the fiber optic array (FOA) which termed MLFOA. This device achieves an impressive resolution of <430nm> $430\mu $

without using any algorithm processing and film, the highest among the compact microscopes to our best knowledge. The material (refractive index, NA), the diameter, the light wavelength, immerse liquid of the microsphere is measured by using the MLFOA. The device can potentially be expandable for the point-of-care testing (POCT) detection.
期刊介绍：
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
