Scientists Developed A Focus-Free Camera With Flat Lenses

Scientists Developed A Focus-Free Camera With Flat Lenses. University of Utah, Salt Lake City, and Oblate Optics, Inc. A team of researchers has created a camera that doesn’t need to focus. The new flat lens can significantly reduce the weight, complexity, and cost of cameras and other imaging systems, increasing its functionality.

University of Utah scientist Drs. Rajesh Menon said: Our flat lenses can reduce the weight, complexity, and cost of cameras and other imaging systems. Such optics can allow for thinner smartphone cameras, enhanced biomedical imaging such as endoscopy, and more compact automotive cameras.

The kit’s flat lenses can focus on objects about 6 meters (20 feet) apart from each other. They use nanostructures modeled on a flat surface instead of heavy glass or plastic to obtain important optical properties that control the way light travels.

Dr. Menon said: This new lens can have many interesting applications outside of photography, such as making highly efficient lighting for LIDAR, which is important for many autonomous systems. The design approach we use can be extended to create optical components with any number of properties, such as excessive bandwidth, simple manufacturing capacity, or low cost.”

Traditional cameras, whether used in smartphones or for microscopy, must be focused to ensure that the detail of an object is sharp. If there are multiple objects at different distances from the camera, then each object should be focused differently. “The new lens eliminates the need to focus and allows any camera to focus on all objects simultaneously,” said Dr. Menon.

“Traditional cameras use multiple lenses to simultaneously retain different colors of focused light. Since our design is very general, we can also use it to create a single flat lens, which focuses all light colors, further simplifying the cameras. “

To focus light, conventional lenses convert parallel light waves into spherical waves that become a focal space. Dr. Menon and colleagues felt that waves with other shapes can produce a similar effect, increasing the number of possible lens designs.

“Unlike what is taught in optics textbooks, our research has shown that light transmission is influenced by an ideal lens, a concept known as pupil action,” he said. “This lens opened up essentially infinite possibilities for pupil function, and we looked for one through these possibilities that achieved extreme depth of focus.”

After choosing the best lens design for depth of focus, the researchers used nanofibrification technology to create a prototype lens. Experiments confirmed that the new lens performed as expected and focused on several orders of magnitude larger than a similar conventional lens.

Scientists demonstrated new lenses using infrared light and relatively low numerical apertures, a number that marks the range of angles at which the lens can accept or emit light. They plan to extend the lens to larger numerical pores and use it with a full spectrum of visible light.

Work to ensure that the lenses can be manufactured on a large scale before they can be marketed. “This research is a good example of how abandoning traditional assumptions can enable devices that were previously considered impossible. Dr. Menon said it serves as a good reminder to ask questions of the past.

Focusless camera made with ultrathin lens. Scientists have created a camera that does not need to focus using a one-inch lens that is about a thousandth of an inch thick. They believe that the technology offers considerable advantages over traditional cameras, as in most smartphones, which require multiple lenses to create high-quality focus images.

“Our flat lenses can reduce the weight, complexity, and cost of cameras and other imaging systems,” said Rajesh Menon, leader of the University of Utah research team. “Such optics can allow for thinner smartphone cameras, enhanced biomedical imaging such as endoscopy, and more compact automotive cameras.”

The new flat lens can focus on objects that are about 6 meters apart. Flat lenses use nanostructures formulated on a flat surface instead of heavy glass or plastic to achieve significant optical properties that control how they fly.

Menon said: “This new lens can have many exciting applications outside of photography, such as building highly efficient lighting for LIDAR, which is important to many autonomous systems, including autonomous cars.”

The researchers say the design approach they use can be broadened to create optical components with any number of properties, such as excessive bandwidth, easy manufacturing capacity, or low cost.

Traditional cameras, whether used in smartphones or for microscopy, must be focused to ensure that the detail of an object is sharp. If there are multiple objects at different distances from the camera, then each object should be focused differently.

“The new lens eliminates the need to focus and allows any camera to hold all objects together,” said Menon. “Traditional cameras use multiple lenses to simultaneously retain different colors of focused light.

Since our design is very general, we can also use it to create a single flat lens, which focuses all light colors, further simplifying the cameras. ” To focus light, conventional lenses convert parallel light waves into spherical waves that become a focal space. In a significant advance.

The new flat lens can maintain focus for objects that are approximately 6 meters away from each other. Flat lenses use nanostructures formulated on a flat surface instead of heavy glass or plastic to achieve significant optical properties that control how they fly.

Traditional cameras, whether used in smartphones or for microscopy, require focus to ensure that the details of an object are sharp. If there are multiple objects at different distances from the camera, each object must be focused separately.

“The new lens eliminates the need to focus and allows any camera to hold all objects together,” said Menon. “Traditional cameras use multiple lenses to keep different colors of light in focus simultaneously.

Since our design is very general, we can also use it to create a single flat lens that focuses all light colors, further simplifying the cameras. “To focus light, conventional lenses convert parallel light waves into spherical waves that become a focal space.”

In a significant advance, the researchers realized that waves with other shapes could produce a similar effect, increasing the number of possible lens designs. Contrary to what is taught in optics textbooks.

Our research has shown that light transmission is more than one way to be affected by an ideal lens: a concept known as the pupil function, “Menon.” This lens opened up infinite possibilities for pupil function. “And we sought through these possibilities one that would achieve an immense depth of focus.”

After choosing the best lens design for depth of focus, the researchers used nanofibrification technology to create prototype lenses. Experiments confirmed that the new lens performed as expected and focused on several orders of magnitude larger than similar conventional lenses.
