Single-exposure holographic 3D printing via inverse-designed phase masks
Dajun Lin, Xiaofeng Chen, Connor O. Dea +8
Additive manufacturing using light is commonly constrained by serial voxel-by-voxel or layer-by-layer processing, which fundamentally limits fabrication speed and scalability. Here…
Four-dimensional video imaging via generative deep learning and a diffuser-encoded image sensor
Max T. Kauss, William Walker, Alexander Ingold +3
Light carries rich information across space, spectrum, polarization, and time, yet conventional cameras capture only a narrow projection of this multidimensional structure. A thin…
Visible to Longwave-infrared imaging via an inverse-designed monolithic lens
Syed N. Qadri, Apratim Majumder, John D. Hodges +3
Chromatic aberrations impose a fundamental barrier on optical design, confining most imaging systems to narrow spectral bands with fractional bandwidths typically limited to $Îλ/…
Wavefront Coding for Accommodation-Invariant Near-Eye Displays
Ugur Akpinar, Erdem Sahin, Tina M. Hayward +3
We present a new computational near-eye display method that addresses the vergence-accommodation conflict problem in stereoscopic displays through accommodation-invariance. Our sys…
Contrary to widespread belief, the Fresnel zone plate outperforms the metalens at high NA
Apratim Majumder, John A. Doughty, Tina H. Hayward Henry I. Smith +1
Rigorous simulations challenge recent claims that metalenses outperform conventional diffractive lenses, such as Fresnel Zone Plates (FZPs), in focusing efficiency at high numerica…
Dynamic Spectral fluorescence microscopy via Event-based & CMOS image-sensor fusion
Richard G. Baird, Apratim Majumder, Rajesh Menon
We present a widefield fluorescence microscope that integrates an event-based image sensor (EBIS) with a CMOS image sensor (CIS) for ultra-fast microscopy with spectral distinction…
