Computational Imaging

Computational Imaging jointly designs optics and algorithms. This field of research is inherently interdisciplinary, combining expertise in imaging science, optical engineering, signal processing and machine learning. Computational imaging can overcome physical limitations and achieve novel capabilities, from advancing experimental observation techniques used in biology, to highly novel imaging system methods to atomic force microscopy. Computational Imaging serves a broad range of scientific, defense and security, biomedical, and neuroscience applications.

Computational Miniature Mesoscope for Cortex-wide, Cellular resolution Ca2+ Imaging in Freely Behaving Mice

Scale is a fundamental obstacle in linking neural activity to behavior. While perception and cognition arise from interactions between diverse brain areas separated by long distances, neural codes and computations are implemented at the scale of individual neurons. An integrative understanding of brain dynamics thus requires cellular-resolution measurements across sensory, motor, and executive areas spanning […]

Lighting the Way Forward for Autonomous Vehicles

CISE Faculty Affiliate Ajay Joshi with collaborators at Lightmatter and Harvard University receive $4.8M IARPA grant to develop a new Electro-Photonic Computing (EPiC) system for  AI-based navigation in Autonomous Vehicles Anyone who has ever been behind the wheel of a car knows that response time is crucial. The human sensory system needs to be fully engaged in order […]

Reflection-mode Computational 3D Phase and Polarization Imaging for Semiconductor Wafer Metrology and Inspection

The goal of this project is to prototype a reflection-mode computational microscope to 1) provide wide field-of-view (FOV) and high-resolution phase reconstruction using a new reflection-mode Fourier ptychography (FP) algorithm; 2) enable 3D phase reconstruction based on a new reflection-mode multi-slice beam-propagation method (MS-BPM) model; and 3) investigate the utility of polarization sensitive contrast in […]

Stealth Driverless Cars without Visible Light?

CISE Faculty Affiliate Professor Vivek Goyal (ECE) recently 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 […]

Local neuronal drive and neuromodulatory control of activity in the pial neurovascular circuit

We seek to understand the nature of the pial neurovascular circuit, whose dynamics is characterized by ultralow frequency oscillations near 0.1Hz that parcellate into separate coherent regions across cortex. We will use this knowledge to form a mathematical relation between the hemodynamic patterns observed in optical and functional magnetic resonance imaging experiments and the underlying […]

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 […]
