About Us
We’re a group of engineers tackling an interesting challenge

Lensless Digital Holographic Microscopy (LDHM) is a novel, cost-effective, and portable solution for high-resolution imaging of microscopic objects. LDHM has emerged as a promising imaging technique for several biomedical applications due to its compact design, cost-effectiveness, and the ability to reconstruct both amplitude and phase information, which can then use these innovative technique to utilize in-line holography, pixel super-resolution, backpropagation, Fourier and inverse Fourier transformations, phase retrieval, and twin image artifact removal to deliver high-quality images. The design incorporates a CMOS sensor, multiple light sources, and other software algorithms to reconstruct an image from its holograms and then enhance image resolution. We will present our study of a modular LDHM system utilizing an LED as the light source, a pinhole, and a CMOS sensor through a Raspberry Pi. The observed images will then use multi-frame pixel super-resolution to increase resolution. This project has the potential to increase interest and access to the field of microscopy and provide new opportunities for research in areas such as oil monitoring in ocean water, air health, and plant health. As the world continues to get increasingly more and more high-tech, the we wanted to decrease the divide between those with access to the new technology and those without. The aim of this project is to bring about access to microscope technology to a wider group of people.
