Researchers use laser light to form a tiny “optical pinhole” inside a nonlinear crystal, which also turns the infrared image into a visible image that a traditional silicon-based camera sensor can ...

Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...

I grew up reading Superman comic books. One of his superpowers was X-ray vision. He could see through opaque objects to detect danger. I was mesmerized by this power. What would you say if I told you ...

(MENAFN- GetNews) Let's begin with a basic idea. All thermal cameras work by detecting heat, not light. This heat is called infrared or thermal energy. Everything in our daily life gives off heat.
