Designing lensless imaging systems to maximize information capture
Leyla A. Kabuli, Henry Pinkard, Eric Markley +2
Mask-based lensless imaging uses an optical encoder (e.g. a phase or amplitude mask) to capture measurements, then a computational decoding algorithm to reconstruct images. In this…
Scalable dataset acquisition for data-driven lensless imaging
Clara S. Hung, Leyla A. Kabuli, Vasilisa Ponomarenko +1
Data-driven developments in lensless imaging, such as machine learning-based reconstruction algorithms, require large datasets. In this work, we introduce a data acquisition pipeli…
High contrast holography through dual modulation
Leyla Kabuli, Oliver Cossairt, Florian Schiffers +2
Holographic displays are a promising technology for immersive visual experiences, and their potential for compact form factor makes them a strong candidate for head-mounted display…
Information-driven design of imaging systems
Henry Pinkard, Leyla Kabuli, Eric Markley +3
Imaging systems have traditionally been designed to mimic the human eye and produce visually interpretable measurements. Modern imaging systems, however, process raw measurements c…
Computationally Efficient Information-Driven Optical Design with Interchanging Optimization
Eric Markley, Henry Pinkard, Leyla Kabuli +2
Recent work has demonstrated that imaging systems can be evaluated through the information content of their measurements alone, enabling application-agnostic optical design that av…
Estimation-theoretic analysis of lensless imaging
Leyla A. Kabuli, Nalini M. Singh, Laura Waller
We analyze lensless imaging systems with estimation-theoretic techniques based on Fisher information. Our analysis evaluates multiple optical encoder designs on objects with varyin…
