Laser engraving device for multiple laser beams using a data link for adjusting the focusing position
The present invention concerns a laser engraving device (1) for engraving a target surface (17). The laser engraving device (1) comprises: a beam splitter (7) for dividing a processing laser beam (25) into a plurality of engraving laser beams (27); a first ...
2022LenslessPiCam: A Hardware and Software Platform for Lensless Computational Imaging with a Raspberry Pi
Martin Vetterli, Eric Bezzam, Sepand Kashani, Matthieu Martin Jean-André Simeoni
Lensless imaging seeks to replace/remove the lens in a conventional imaging system. The earliest cameras were in fact lensless, relying on long exposure times to form images on the other end of a small aperture in a darkened room/container (camera obscura) ...
2022Regional Differences in the Perception of Daylit Scenes across Europe Using Virtual Reality. Part II: Effects of Facade and Daylight Pattern Geometry
Marilyne Andersen, Jan Wienold, Kynthia Chamilothori
While there is a growing use of complex facade designs in contemporary architecture worldwide and across Europe, little is known about the perceptual effects of these facades and the resulting daylight patterns on occupants, or about how such effects might ...
TAYLOR & FRANCIS INC2022SLITRONOMY: Towards a fully wavelet-based strong lensing inversion technique
Frédéric Courbin, Aymeric Alexandre Galan, Austin Chandler Peel, Rémy Elie Joseph
Strong gravitational lensing provides a wealth of astrophysical information on the baryonic and dark matter content of galaxies. It also serves as a valuable cosmological probe by allowing us to measure the Hubble constant independently of other methods. T ...
EDP SCIENCES S A2021High-Resolution Multi-Spectral Imaging With Diffractive Lenses and Learned Reconstruction
Oguzhan Fatih Kar, Can Deniz Bezek
Spectral imaging is a fundamental diagnostic technique with widespread application. Conventional spectral imaging approaches have intrinsic limitations on spatial and spectral resolutions due to the physical components they rely on. To overcome these physi ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Single-shot observation of breathers from noise-induced modulation instability using heterodyne temporal imaging
We report phase and amplitude measurements of large coherent structures originating from the noise-induced modulation instability in optical fibers. By using a specifically designed time-lens system (SEAHORSE) in which aberrations are compensated, the comp ...
OPTICAL SOC AMER2021Fixed-wing micro UAV open data with digicam and raw INS/GNSS
Jan Skaloud, Davide Antonio Cucci, Kenneth Joseph Paul
We have recently released in the open domain data originating from a series of flights conducted with a fixed-wing micro UAV carrying high-quality small camera and navigation sensors. This data was previously used in several peer-reviewed publications. How ...
2021Measuring accretion disk sizes of lensed quasars with microlensing time delay in multi-band light curves
Frédéric Courbin, Martin Raoul Robert Millon, Hung-Hsu Chan, Vivien François Bonvin, Karina Alexandra Rojas Olate
Time-delay cosmography in strongly lensed quasars offers an independent way of measuring the Hubble constant, H-0. However, it has been proposed that the combination of microlensing and source-size effects, also known as microlensing time delay, can potent ...
EDP SCIENCES S A2021Koehler integrator device and application thereof in a multi-focal confocal microscope
Suliana Manley, Kyle Michael Douglass, Dora Mahecic
A Koehler integrator device (10) comprises a collimating lens (11) being arranged for collimating a light field created by an incoherent or partially coherent light source, a pair of planar first and second micro-lens arrays (12, 13) being arranged for rel ...
2020Precise Hand Finger Width Estimation via RGB-D Data
We propose a novel application of pose estimation to precisely measure the hand finger width via noisy RGB-D image. A framework is developed that estimates the finger width given data from TrueDepth camera as well as the target finger measure- ment location. ...
