Improving Mid-Infrared Imaging and Sensing

Artificial optical materials could allow cheaper, flatter, more efficient detectors for night vision and other uses. A new way of taking images in the mid-infrared part of the spectrum, developed by researchers at MIT and elsewhere, could enable a wide variety of applications, including thermal imaging, biomedical sensing, and free-space communication. The mid-infrared (mid-IR) band

Researchers Combine Metalens With an Artificial Muscle

Artificial eye automatically stretches to simultaneously focus and correct astigmatism and image shift. Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the
