Lensless Camera Uses Fresnel Zone Aperture, Incoherent Illumination to Improve Images To reduce noise in a thin, lensless camera, researchers at Tsinghua University and MIT built an imaging system with a Fresnel zone aperture (FZA). In addition to introducing a Fresnel optical element into the camera, the researchers used a compressive sensing algorithm to improve the quality of reconstructed images. Read Article

Avalanche Photodiode Is High-Power and Eye-Safe for Lidar A low-noise avalanche photodiode (APD) for 2-µm detection, developed by engineers at the University of Virginia (UVA) and the University of Texas-Austin (UT-Austin), could provide high-power, eye-safe light imaging, detection, and ranging for lidar applications. According to the team, the new APD has demonstrated record performance. Read Article

.: Featured Products   HyperFine Brillouin Spectrometer LightMachinery Inc. The great challenge with Brillouin spectroscopy is that the scattered signal from the un-shifted wavelength of the laser can overwhelm the small Brillouin shifted return signal. LightMachinery has combined its leading-edge HyperFine spectrometer with a very narrow band tunable filter to suppress the bright un-shifted laser frequency.  Visit Website   Request Info  Wavelength Stabilized Laser Diode PhotonTec Berlin GmbH PhotonTec Berlin expands its wavelength stabilized diode family with a new high-brightness 976 nm diode of 140 W power from a 105 µm core and 0.22NA fiber pigtail. Utilizing volume grating, the emitting wavelength is stabilized at 976 nm and insensitive to operating temperature and current.  Visit Website   Request Info

.: Upcoming Webinars   A New Approach to Interferometry: Unlocking New Possibilities in UV/VIS Spectroscopy Wed, Jun 17, 2020 10:00 AM - 11:00 AM EDT This webinar will describe ultrastable, common-path (CP) interferometry and how CP interferometry can provide all the advantages of Fourier-transform spectroscopy down to the UV-VIS spectral regions, in a compact device. The operation principle of a CP interferometer will be presented, together with a few applications, such as the measurement of Time-Resolved Emission Spectra (TRES) with picomolar sensitivity and Excitation-Emission Maps (EEM) down to the ultimate sensitivity, by detecting fluorescence/EEM of single molecules at room temperature. Finally, novel applications of the interferometer for hyperspectral imaging will be presented.  Register Now  .: All Things Photonics   In the final episode of Season 1 of All Things Photonics, Tom Hausken, senior industry advisor from OSA, reviews the photonics market and its recovery from the COVID-19 pandemic. Also, more from Coherent’s new CEO Andy Mattes and COO Mark Sobey. Listen Now   CALL FOR ARTICLES!
