A group of researchers has developed a new camera that is sensitive enough to detect a single photon with significantly more resolution than any other like it.
A group of researchers has developed a new camera that is sensitive enough to detect a single photon. This large photon camera isn’t unique in its purpose, but separates itself thanks to its ability to capture 400 times the resolution of previous photon cameras., the camera is designed to capture single photons — tiny particle composed of electromagnetic waves that are the basic units that make up light . Microwaves and X-rays are both made up of photons, for example.
But the researchers have changed that with their superconducting-nanowire single-photon camera that is capable of producing images at 400,000 pixels. This camera is now the largest of its type ever designed and its pixel array is 400 times larger than the previous largest photon camera.explains that this camera can work at various light frequencies from the visible to ultraviolet and infrared and can capture at super high-speed frame rates — as fast as a matter of picoseconds.
“In exoplanet direct imaging, you are attempting to image planets that are millions of times fainter than their parent stars. It’s the equivalent of trying to see a firefly next to a fully lit football stadium from a plane,” Sarah Steiger, a doctoral student who works with noted optical sensor expert Ben Mazin of the University of California, Santa Barbara, explains.
