Optofluidic microscopy - A method for implementing a high resolution optical microscope on a chip [PDF]
We report a novel microfluidics-based lensless imaging technique, termed optofluidic microscopy (OFM), and demonstrate Caenorhabditis elegans imaging with an OFM prototype that gives comparable resolution to a conventional microscope and a measured ...

Advances in Mask-Modulated Lensless Imaging
Lensless imaging allows for designing imaging systems that are free from the constraints of traditional imaging architectures. As a broadly investigated technique, mask-modulated lensless imaging encodes light signals via a mask plate integrated with the

Digital lensless holographic microscopy and applications
, 2017 Abstract The principles and some applications of the digital lensless holographic microscopy (DLHM) to study the microworld are shown in this paper. The recording and reconstruction processes of the DLHM are analyzed to study its lateral resolution power.

Privacy-Enhancing Optical Embeddings for Lensless Classification [PDF]
Lensless imaging can provide visual privacy due to the highly multiplexed characteristic of its measurements. However, this alone is a weak form of security, as various adversarial attacks can be designed to invert the one-to-many scene mapping of such ...

Motion-free high-resolution on-chip microscopy using LED matrix
Lensless microscopy is an imaging technique that allows high-resolution imaging over a large field of view with a cost-effective design. Conventional lensless microscopy often utilizes multi-height phase retrieval and pixel-super-resolution algorithms to
