In a darkening world, the future depends on light.
For the International Day of Light 2022, we created a fictional movie trailer to highlight the real technologies that make our world a better place.
About the movie
Our world is falling into darkness – dirty energy, illness, climate change, global hunger, tainted water. With the power of optics and photonics – the science and application of light – we can fight back the darkness. We can fight climate change, sense danger before it strikes, build tools to solve the unsolvable, and see the unseen.
What critics are saying
“Brilliance from beginning to end. Radiating performances.
5 out of 5 stars”
— Glowing Reviews
“An illuminating look into our future. A shining example of cinema at its brightest.”
— Daily Waves
Let’s shed some light on the movie
Okay, okay. Day of Light is not a real movie, but the issues it addresses are real and you can be a part of the solution. The technology and industry already exist, we just need the team to help fight the fight. Check out the rest of this website to learn more about light-based technology and how you can play your part.
Technologies in the movie
Solar energy
Solar energy – or sunlight – is the most abundant energy resource on Earth. 173,000 terawatts of solar energy strike the Earth continuously. That's more than 10,000 times the world's total energy use at any given moment.
A solar farm is a large collection of photovoltaic (PV) solar panels that absorb that energy from the sun, convert it into electricity, and send that electricity to the power grid for distribution and consumption by customers. And it’s a clean energy source, generating no emissions or pollution!
Lidar
Maybe you have heard of lidar as one way we can have safe, self-driving cars or autonomous vehicles. But lidar has many more applications that can help solve some of our biggest global issues.
Lidar, or Light Detection and Ranging, is a remote sensing method that uses laser light reflecting off objects to measure distance, whether the object is another car, a building, a person, particles in the wind, or the dimensions of an ice shelf in Antarctica. The 3D data generated can, for instance, help hazard assessment including lava flows, landslides, tsunamis, and floods.
Spectral imaging
Did you know that an ordinary camera captures light across three wavelength bands in the visible spectrum: RGB or red, green, and blue? Spectral imaging combines photography with spectroscopy to sample image data across the entire electromagnetic spectrum.
One type - hyperspectral imaging - is becoming widely popular for tracking changes in the environment. We can combat climate change because hyperspectral imaging helps us understand surface CO2 emissions, map hydrological formations, track pollution levels, detect leaks, ensure food quality, and more.
Femtosecond lasers
When you think of lasers, what springs to mind? Cats and laser pointers or sci fi movies? Lasers have a long history of productive uses from industrial cutting and welding, to CD players, to beaming video across fiber optic cables or between satellites using fast laser pulses.
The word laser is an acronym for "light amplification by stimulated emission of radiation." A femtosecond laser is an infrared laser that emits bursts of laser energy at an extremely fast rate. Medicine is being transformed thanks to this ultrafast laser which promises highly accurate, uniform, and predictable laser surgery techniques.
8K Resolution
VR is a completely immersive, visual, and sound-based experience. Gaming is maybe the best-known use for virtual reality (VR), but its potential doesn’t stop there. VR can be used in all types of training scenarios – such as military, medical, or remote classrooms – allowing for a huge range of simulations that are both safer and more cost effective.
Both augmented reality (AR) and VR systems rely on light engines, which generate images for display. High resolution and brightness are important requirements for these components and 8K resolution is the latest iteration. Combined with AR and VR, 8K resolution promises greater presence and realism leading to a more immersive and reliable experience for users.
