Apple releases new Pro Display XDR Calibrator in Display Firmware 4.2.30 update

For the the Pro Display XDR, Apple today released a new Display Firmware 4.2.30 update which introduces a new Pro Display XDR Calibrator for in-field recalibration.

With Retina 6K resolution, gorgeous color and extreme brightness and contrast ratio, Pro Display XDR is the world’s best pro display.

The Apple Pro Display XDR is the first 32-inch Retina 6K display ever. Up to 1600 nits of…

As climatic change and land use are altering the hydrographic regime, most catchments are progressively becoming drier and farmers are shifting from rainfed agriculture to irrigation practices to enable them to carry out income-generating activities throughout the year. The Ghanaian government has recently been promoting irrigation agricultural practices as the population keeps increasing and the demand for food keeps soaring. In order to keep pace with high demand for food coupled with increasing aridity of the subregion, some farmers resort to informal irrigation practices. In this study, hyperspectral reflectance data of the irrigated crops under informal practices were collected to assess their efficiency of water use. Photochemical reflectance index (PRI), soil-specific nitrogen index (SSN), and water band index (WBI) were computed. The PRI and WBI were significantly correlated, while there was no significant correlation between PRI and SSN. The map showing the probability of water stress indicated that informal irrigation practices are not an efficient water management approaches.

As the performance and quality of displays increase, so does the demand for test instrumentation standards. In addition, with the rapid development of some other types of illuminated elements, for example, Organic EL as well as conventional LCD and PDP displays, there is a requirement for high-precision spectral radiation curve analysis.

 RayClouds provides accurate spectroradiometers to  meet your display measurements.

 Application of Spectroradiometer

Spectroradiometer widely used in FPD display, backlight, lighting engineering, light source and lighting devices, film and TV, traffic signals, construction, atmospheric luminosity and other fields.

NASA Captures North Sea Algae In Full Bloom

Every summer, the population of algae in the North Atlantic reaches a peak, with the blue-green color of the phytoplankton causing the ocean to visibly change, even from space. NASA’s aptly-named Aqua satellite captured the above image on July 1st using its Moderate Resolution Imaging Spectroradiometer instrument. You can see Norway on the right, the UK peeking out from under the clouds on the…
