May 3, 2022 · A lensless camera, which comprises an image sensor and a thin mask in front of the sensor that encodes information from a given scene, requires mathematical reconstruction to produce a detailed image.

Mar 30, 2024 · This review provides the principles and prospects of lensless camera, with emphasis on latest breakthroughs in optical modulation elements, image sensors, and reconstruction algorithms. Currently, traditional optical components pose notable constraints.

Apr 28, 2022 · Recent advances in computing technology can simplify the lens system by substituting computing for some parts of the optical system. The entire lens can be abandoned thanks to the use of image...

Feb 10, 2022 · In this post, we go through all the steps to build and use a lensless camera, specifically a modification of the DiffuserCam [1] proposed by Prof. Waller’s group at UC Berkeley that we call...

Jan 28, 2020 · As explained in a paper published on Optics Express, it is possible to create a camera without a lens focussing light rays coming from a specific point in space on a specific pixel (this is what a lens does).

Under-display cameras, micro-robotic vision, implantable sensors, and virtual/augmented reality headsets are some of the upcoming exciting applications that can benefit from the form factor of lensless cameras.

May 4, 2022 · Using a new design that relies on machine learning, a lensless camera could be so small as to be invisible.

Sep 7, 2022 · Lensless camera creates 3D images from single exposure. Real-time 3D imaging method could improve robot navigation and content for 3D displays. WASHINGTON—Researchers have developed a camera that uses a thin microlens array and new image processing algorithms to capture 3D information about objects in a scene with a …

May 7, 2022 · “The ultimate goal of a lensless camera is being miniature-yet-mighty. We are excited to be leading in this new direction for next-generation imaging and sensing solutions,” says the lead author of the study, Mr. Xiuxi Pan of Tokyo Tech.

Jun 21, 2017 · At Caltech, engineers have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it manipulates incoming light to capture an image.
