this light field camera inspired by an extinct trilobite promises high-resolution image with extreme depth of field

Researchers have developed a nanophotonic light field camera that's based on the eye of an extinct Cambrian-era trilobite, Dalmanitina socialis, that delivers an extreme depth of field. The camera has a depth of field ranging from a centimeter to a kilometer scale. The camera utilizes a multiscale convolutional neural network-based reconstruction algorithm to eliminate optical aberrations that result from the camera's 'metalens' array. The project is described in excellent detail in a new resear...
