This study aimed at the development and validation of an accurate, more affordable, precise digital imaging resazurin-based fungicide sensitivity colorimetric assay (COL-assay) for fungal plant pathogens from genera Mycosphaerella Pyricularia. proposed was based on estimates resazurin reduction, which used as a metabolic indicator respiration activity microplate cultures. As model systems, we y...

A fluorescence-based integrated optics microfluidic device is presented, capable of detecting single DNA molecules in a high throughput and reproducible manner. The device integrates microfluidics for DNA stretching with two optical elements for single molecule detection (SMD): a plano-aspheric refractive lens for fluorescence excitation (illuminator) and a solid parabolic reflective mirror for...

Scanning illumination systems provide for a powerful and flexible means for controlling illumination coherence properties. Here we present a scanning Fourier synthesis illuminator that enables microfield extreme ultraviolet lithography to be performed on an intrinsically coherent synchrotron undulator beamline. The effectiveness of the system is demonstrated through a variety of print experimen...

We have been investigating the use of supercontinuum (SC) laser technology to provide active illumination for shortwave infrared (SWIR) hyperspectral sensors in order to extend their operational window into the night and heavy overcast periods. Unlike a lamp, light from a broadband laser illuminator (BLI) can propagate long distances through the atmosphere while maintaining its spatial coherenc...

We present the potential optical performance capabilities of a next-generation extreme ultraviolet (EUV) mask-imaging microscope, based on the proven optical principle of the SEMATECH Berkeley Actinic Inspection Tool (AIT), but surpassing it in every performance metric. The new synchrotron-based tool, referred to here as the SEMATECH Berkeley Actinic Imaging Tool at 0.5 NA (AIT5) will enable re...

Crenits Bedel is a small hydrophilid genus of 41 species (Hansen, 1999; Hebauer, 1994, 2005), distributed across Eurasia, Africa and the Americas. The genus is particularly diverse in temperate regions, with the eastern Palaearctic and Nearctic regions containing the highest concentrations of taxa. The eight described African species are all restricted to temperate South Africa, most being foun...

In recent years, the iris recognition system has been gaining increasing acceptance for applications such as access control and smartphone security. When the images of the iris are obtained under unconstrained conditions, an issue of undermined quality is caused by optical and motion blur, off-angle view (the user's eyes looking somewhere else, not into the front of the camera), specular reflec...

Abstract The article describes the laser safety classification of a toy for children equipped with aimer/illuminator two radiation sources. Following rules presented in EN 60825-1: 2014 standard, tests and measurements accessible emission were carried out class product was determined to be 3R. It shown that does not comply requirements 62115: 2020 standard Public Health England Guidance. potent...
