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 ...

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 ...

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 ...

A researcher has developed a new technique to detect long wave infrared (LWIR) photons of different wavelengths or 'colors.' The new detection and imaging technique will have applications in analyzing ...

An optical/electric dual-mode photodetector array for human–machine collaborative infrared imaging was demonstrated. The responsivity of the photothermoelectric photodetector was improved by the ...

The LUMOS II ILIM features a patented coherence reduction method for infrared laser imaging essentially free from artifacts in both transmission and reflection mode. With a very large field of view ...

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 ...
