Optogenetic modulation of brain neural activity that combines optical and electrical modes in
a unitary neural system has recently gained robust momentum. Controlling illumination …

Lensless imaging provides opportunities to design imaging systems free from the constraints
imposed by traditional camera architectures. Due to advances in imaging hardware …

The simple and compact optics of lensless microscopes and the associated computational
algorithms allow for large fields of view and the refocusing of the captured images. However …

The ability to simultaneously image the spatiotemporal activity signatures from many
neurons during unrestrained vertebrate behaviors has become possible through the …

Miniature fluorescence microscopes are a standard tool in systems biology. However,
widefield miniature microscopes capture only 2D information, and modifications that enable …

We demonstrate a versatile thin lensless camera with a designed phase-mask placed at sub-
2 mm from an imaging CMOS sensor. Using wave optics and phase retrieval methods, we …

Mask-based lensless imagers are smaller and lighter than traditional lensed cameras. In
these imagers, the sensor does not directly record an image of the scene; rather, a …

Lensless imaging has emerged as a potential solution towards realizing ultra-miniature
cameras by eschewing the bulky lens in a traditional camera. Without a focusing lens, the …

Here we present a fluorescence microscope light path that enables imaging, during free
behavior, of thousands of neurons in mice and hundreds of neurons in juvenile songbirds …

Histopathology plays a critical role in the diagnosis and surgical management of cancer.
However, access to histopathology services, especially frozen section pathology during …
