Time‐Domain Raman Spectroscopy: An Emerging Technique in Space Exploration?

Journal of Raman Spectroscopy, EarlyView.
The potential of time‐domain Raman spectroscopy in space exploration is discussed. This work is motivated by the emergence of robust, space‐qualified femtosecond lasers and by the fact that time‐domain detection allows the design of very compact instruments, while avoiding problems such as fluorescence or ambient light backgrounds (inset: ESA/DLR/FU ...

Harnessing deep learning for wheat variety classification: a convolutional neural network and transfer learning approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Computer vision and the use of image‐based solutions are gaining traction as non‐destructive food assessment methods because of the low costs of computational equipment. Research conducted on the development of wheat classification models has been based on limited data and a smaller number of classes compared to the availability of ...

Programmable Dual‐Wavelength Switchable All‐fiber Laser via Hybrid Optical Amplifier in the NIR‐III Region for Multi‐Contrast Photoacoustic Microscopy

Laser &Photonics Reviews, EarlyView.
A novel dual‐wavelength switchable all‐fiber laser operating in the NIR‐III region, utilizing a hybrid optical amplifier, is presented. This laser generates high power‐spectral‐density pulses with flexible pulse widths and high switching frequencies, enabling efficient multi‐contrast photoacoustic microscopy for the detection of microplastics in ...

Multi‐Octave All‐Dielectric Directional Coupler Using Integrated Half‐Mirror for Ultrawideband Terahertz Systems

Laser &Photonics Reviews, EarlyView.
Fully exploiting the broad untapped terahertz spectrum necessitates extending the bandwidth of practical guided‐wave systems. This work introduces a substrateless quasi‐optical integration platform to meet this need. Classical optical principles going back to the time of Michelson are adapted to a planar, micro‐machined, monolithic‐silicon platform ...
