A team of researchers in China has developed a lens-free imaging system that produces sharp mid-infrared images even in low light and across long distances. The breakthrough promises improvements for ...

Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a ...

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 ...

The ability to detect infrared radiation is the basis of any infrared thermal imaging technology. All objects emit infrared radiation as a function of their temperature; the detection of such ...

Infrared imaging also supports non-destructive testing across industries such as automotive, electronics, and construction. Its integration into automated systems and Industry 4.0 frameworks and the ...

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 ...
