CCSS: Signal Processing for Single-Photon Detectors

Light has a fundamental smallest quantity – a photon – that is very far from everyday human experience. For example, the number of photons collected by the camera in a mobile phone to form a typical photograph is in the trillions. Nevertheless, there are some increasingly common devices that rely on measuring light down to […]

Super Headlights: Superconducting Nanowire Detectors for Passive Infrared Sensing

CISE Faculty Affiliate Professor Vivek Goyal (ECE) received a Defense Advanced Research Projects Agency (DARPA) subaward for his work in connection with the agency’s Invisible Headlights program. Professor Goyal is working under an award to MIT entitled, “Super Headlights: Superconducting Nanowire Detectors for Passive Infrared Sensing.”  The DARPA Invisible Headlights program has a very ambitious […]

CIF: Small: Sequential and Compound Estimation for Computational Imaging Systems

The widespread use of imaging technologies across biology, chemistry, material science, medicine, and other fields is motivated by the great innate human ability for visual information processing. Imaging is often limited, however, by the damage to a sample caused by the imaging process, such as sputtering due to the incident ion or electron beam in […]

CIF: Small: Low-Light 3D Imaging: From Fundamental Limits to Practical Systems

Forming images with focused, spatially resolved light is an area of rapid innovation due to the growing use of computational methods and the variety of meanings of ?image.? Aside from being photograph-like, an image acquired through optical means could show distances, thicknesses, chemical concentrations, molecular energy transfers and many other properties, depending on the methods […]

CIF: Small: Quantization for Acquisition and Computation Networks

Networks of sensors are increasingly important in a variety of applications including national security, environmental monitoring, and health care. These systems should serve their purposes with minimal communication between sensors and minimal computation overhead from coding. In particular, these efficiencies can dramatically improve battery life, and in systems such as those implanted in a body, […]
