Recently, Basu and Holstlag (2021) proposed a unified f ramework f or describing outer length scales (OLS). By utilizing this framework, we document various characteristics of OLS in nocturnal boundary layers over the US Great Plains.

Standard ecotoxicological tests are compared to delayed-luminescence tests, of algae samples (R. subcapitata), showing that the photonic approach can be as reliable as and more precocious than the standard one, here demonstrated for solutions of Durion. The main drawback is to determine the initial (best) control sample population (~106 cel/mL).

We propose a fully differentiable optical design method enabled by curriculum learning. Preliminary results show that our framework is suitable to solve highly non-convex problems like cellphone lens design.

This study analyses the solar noise effects on flash lidar systems for several visibility conditions. The Monte-Carlo radiative transfer method is used for the signal to noise ratio (SNR) calculation, and it is confirmed that the solar noise has adverse effects on the operation of the systems, giving rise to about 3 - 5 dB decrease in SNR.

Neural Networks have been proven successful in many fields. Optical systems show potential for high-speed low-power Neural Networks. However, optical alignment is very demanding for wavelength-level coherent systems. Here we present Training-on-System methods to learn the imperfectly aligned system to increase the system’s performance.

Image-based geolocation can provide vehicle positioning independent of GPS. We model positioning performance using triangulation from geo-referenced landmarks pre-selected from geospatial databases. We describe the accuracy and availability of this navigation implementation.

Digital photoelasticity requires demodulating stress fields, wrapped into color fringe patterns. As an alternative to traditional methods, deep convolutional neural networks are trained to recover stress maps from isochromatic images related to different orientations of a polarized camera, reaching high precision in different analytical models.
