Hybrid Event and Frame-based System for Target Detection, Tracking, and Identification Abstract A hybrid event-based (EBS) and frame-based sensor system is constructed for the task of automated object search and track. Due to its relatively low read-out bandwidth and high temporal resolution, an EBS sensor with a wide field of view (FoV) is employed to monitor a scene and rapidly detect moving targets. A pan/tilt stage holding a frame-based sensor is driven using positional information extra...

Integration of Event-Based Sensing With Traditional Imaging Approaches Abstract The neuromorphic Event-Based Sensor (EBS) is an imaging sensor that asynchronously outputs imaging data as events only when and where a temporal change in scene radiance is detected. An advantage of EBS is its lower read-out bandwidth (up to orders-of-magnitude) relative to equivalently sized conventional frame-based sensor. This readout bandwidth advantage directly leads to related potential advantages such as l...

Optically Enhancing Event-Based Vision Abstract As an asynchronous imaging sensor with integrated change-detection capabilities, EBS can detect temporal changes in scene brightness as they are happening. However, its capability to detect these changes is implemented in electronics and limits the ability to detect low-contrast objects and generates significant noise, both of which hinder the ability to detect objects of interest. Optical spatial high-pass filtering, and optical photocurrent b...

Micro to Macro Optical Signatures for Security Applications Abstract Increasing the performance of a security system to reduce risk is an important task in many applications. In cybersecurity, physical unclonable functions (PUFs), with their unique identity and random property, are excellent candidates to replace the vulnerable pseudo-random signatures. Optical PUFs, consisting of non-integrated circuit with high complexity, provide non-replicable strong signatures for the authentication met...

Quantum-Inspired Optical Super-Resolution Imaging with Modal Measurements Abstract One of the goals of a traditional imaging system is to acquire image of the scene with the highest-resolution possible to infer relevant details or features. However, the traditional imaging approach employs a digital focal plane to capture the optical image at or near the diffraction limit followed by electronic-domain post-processing, which is known to be sub-optimal for many tasks (e.g., classification). Us...

Scatter Based Novel Imaging Systems Abstract Direct imaging refers to an image formation process where an object’s or scene’s optical properties can be spatially/temporally mapped using direct (isomorphic) interaction with ambient or active illumination. However, in many scenarios direct imaging is not feasible or possible, forcing us to utilize scattered photons that only indirectly interact with an object/scene. In this work, we explore two special cases of indirect imaging and propose nov...
