Applications

Image-white balance testing: Colour-replacement tests are proposed to be performed by a variety of conventional A, H, D50, D65, D75 photo-sources, etc. Image-based reality tests: tests of actual scenery by changing various light environments Low-photometry tests: tests of low-level LED sources, low-level tests of low-photo-lighting, photo-coloured tests of 24 colour-based (selected)-side-sorted insulation of the object, by preparing a range of colour-to-light profiles, by calibrating the colour-resilient back-to-earth tropics, by measuring the colour-resight array, by ensuring consistency and accuracy of colour performance. Low-photo-environment tests support for individual-modified LED-based tests of light, e.g., LED-light levels, which can be used below 25 lux, by measuring the critical-specific magnitude of the photo-based lasers, by measuring extreme magnitude. Quantification of scenery: Depth validation in multiple scenes. Multiple scenery sets can be placed in light-source boxes to allow for the application of different colour temperatures, light and single-colour light environments by adjusting the spectrum; based on rapid switching performances in LED channel 30 ms, and accurate validation of dynamic indicators such as white-balanced deposition speed of camera models, which fully cover the quantitative test needs in the scene.

Key Features

Independent channel adjustment: 32 visible-to-near-infrared LED channels each provide 60000 brightness levels. With a spectrometer, spectral fitting reproduces CIE A, H, D50, D65 and D75 over 2000K–20000K. Built-in spectra: the touchscreen recalls A, H, D50, D65 and D75 at 100 brightness levels each without a computer or spectrometer; fluorescent tubes each provide 200 brightness levels. Automatic calibration uses a built-in spectral instrument to compensate for aging and environmental changes. LED channels: 32. Spectrum: 380–980nm. Color temperature: 2000K-20000K. Fluorescent lamps: CWF / TL84. A built-in spectrometer supports custom spectra. Standard-illuminant reproduction covers Planckian radiators, including CIE A, and CIE D daylight spectra from 2000K to 20000K. The 32 adjustable channels cover 380-980nm for flexible simulation. Radiant power can be adjusted to the required illuminance while maintaining spectral quality. An external spectral measurement instrument enables automatic calibration to compensate for spectral changes caused by aging or environmental variation. Timing mode combines spectra and emission durations into automatically switching sequences. Users can measure an environment's spectrum with a spectrometer and import it for reproduction, standardizing or recreating test illumination. Software includes source generation, calibration, spectrometer display and channel-setting modules, with an API(C/C++) for further development. GUI or API control adjusts individual channels or arbitrary multichannel combinations. Integrated TL84 and CWF fluorescent tubes reproduce fluorescent spectra more accurately.
