24‐1: Can Light Microscopes Really Be Chip‐Sized?

Light microscopy has changed considerably over the last century. Nevertheless, it still suffers the limitation of being performed in laboratories, what causes delays to results, partial sampling and non‐continuous measurements. Here we will demonstrate chip‐sized microscopes produced only with microelectronic technologies. With a LED micro‐display as a main component and a photodetector, both raster and multi‐holographic lensless microscopes were demonstrated. The field of view of the microscopes is given by the micro‐display area while LED size limits the resolution. Their low cost in volume manufacturing and chip‐sized compactness will allow ubiquitous microscopy soon. [ABSTRACT FROM AUTHOR]
