The invention of the electric light bulb changed the world, enabling human activity to continue 24 hours a day in all ambient conditions. Today, the lighting design industry is adopting Human Centered Lighting approaches, and considering ergonomics, health and safety, aesthetics, and more. For lighting designers, measuring luminance and color temperature are key to meeting the needs of any environment to optimize human productivity and well being. Learn about tools to capture photometric data and generate IES and EULUMDAT (LDT) files for use with most optical design software packages.

As the display industry is increasing the pixel density of display screens, there is a growing need for precise, high-resolution measurement methods to ensure quality of these displays. Modern imaging systems need to have more measurement pixels (sensor pixels) to increase resolution and capture enough detail to detect defects. Sensor resolution alone isn't all that matters, however, pixel size (well depth) and image noise are just as important for accurate display metrology.

Gestures are a natural and intuitive part of human communication and expression. Thus, being able to use gestures to communicate with devices in our environment has been a goal for technology developers for decades, but it's a complex process. The latest generation of gesture sensing systems include applications in the automotive, medical and consumer spheres, often using three-dimensional / depth sensing based on near-infrared (NIR) light.

The beauty of the automotive space is that there are so many practical applications for displays where benefits can be immediately realized. For example, displays may be the optimal HMI to replace what is already a wealth of analog components (buttons, knobs, gauges) within the vehicle. However, traditional rectangular and even flat-panel freeform displays limit the extent to which displays can be integrated into the vehicle design. This is where curved displays come in, offering the dimensionality to match any surface of the vehicle interior for seamless design.

Augmented reality is helping to advance safety and efficiency in medicine and healthcare, from both the provider and the patient sides. It has already led to changes in areas such as minimally invasive surgery, medical education, diagnostics, medication adherence, and disease detection. One of the biggest breakthroughs provided by new AR applications is their ability to present three-dimensional visualizations using the data from traditional 2D medical imaging technologies like ultrasound, X-ray, and MRI. Learn about some of the latest healthcare AR applications.

Electronic paper (aka e-paper, e-ink, and electrophoretic display) is a unique visual display technology designed to replicate the look of ink printed on paper. Compared to traditional LCD, LED or OLED displays, e-paper is extremely energy efficient and easy on the eyes, lending itself to a ream (pun intended) of new signage and labeling applications beyond its original use in e-readers such as Kindle and Nook.

With all the places you find digital displays these days, evidence suggests it might not be that hip to be square. Displays that break the mold of the standard rectangular, flat-panel design enable a highly organic integration of display features into shapes and sizes that are a much better fit with their use and environments. Non-rectangular displays are also called freeform displays (sometimes “free form” or “free-form” – pick your poison), denoting their bespoke shapes and alluding to the freedom of design that they offer to device makers.
