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…
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 $Δλ/λ<…
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…
Active laser cooling of a centimeter-scale torsional oscillator
Dong-Chel Shin, Tina M. Hayward, Dylan Fife +2
Experimental tests of gravity's fundamental nature call for mechanical systems in the quantum regime while being sensitive to gravity. Torsion pendula, historically vital in studie…
HD snapshot diffractive spectral imaging and inferencing
Apratim Majumder, Monjurul Meem, Fernando Gonzalez del Cueto +4
We present a novel high-definition (HD) snapshot diffractive spectral imaging system utilizing a diffractive filter array (DFA) to capture a single image that encodes both spatial…
FDTD-based Inverse Design enables f/0.27 flat Microlens Array for Integral Imaging
Tina M. Hayward, Robert Stewart, Rajesh Menon +1
We demonstrate a high-NA (0.88), ultra-low-f-number (f/0.2714), multi-wavelength (480nm, 550nm and 650nm) multilevel diffractive MicroLens Array (MLA) using inverse design. Each mi…
