Electromagnetic radiation from the sun--including both the visible light spectrum, and invisible wavelengths such as infrared and ultraviolet--is all around us. Recently scientists have found many uses for certain parts of the light spectrum, such as tapping into the UV spectrum's ability to kill germs, and the beneficial effects of certain green wavelengths to humans.

The interior lighting of an automobile has both a functional and aesthetic purpose. Ambient light can affect driver focus and thus safety, and lighting features like buttons and controls can make it easier to operate a vehible at night. With the advent of LEDs and other new technology automotive designers are creating new and innovative lighting approaches—that must be rigorously tested to conform with industry standards.

Human vision is one of the marvels of the natural world—we can see detail in high resolution at near and far distances with accurate depth perception. We also have a high sensitivity to color across the spectrum of electromagnetic light from wavelenghts of roughly 380 to 740 nm. How does what we see compare to various members of the animal kingdom? And how do we measure and quanitfy vision and color perception? Read more...

Todays consumers expect the highest quality from devices like smartphones, televisions and laptops—and not only for diplay screens the but for keyboards. Manufacturers of laptops and keyboards need to perform precision visual inspection of these devices during the assembly process to ensure that defective products don’t end up in customer hands. Cosmetic flaws and performance failures can result in rapidly escalating direct and indirect costs due to warranty claims, returns, and damage to brand reputation.

Human perception is the ultimate standard for determining the visual quality of a display. However, using human inspection can be problematic because of the statistical variation between observers. Advances in photometric technology and image processing in the last decade have provided an inspection alternative that can match the level of visual acuity of the human eye to detect display defects, but with the speed and consistency of automation. Learn more from our article published in Quality Magazine.

The ultimate measure of display's performance is how it appears to a human viewer. While all of the typical electronic display metrics—ppi, refresh rate, luminance, pixel pitch, etc.—are informative, being able to measure and grade display defects using the Just Noticeable Difference (JND) method is key for display manufacturers to ensure quality.
