Light scattered from the glass cover on the sensor and imaged by the sensor results in a blobby, seemingly formless pattern on the sensor....

A new biosensor allows researchers to track oxygen levels in real time in 'organ-on-a-chip' systems, making it possible to ensure that such systems more closely mimic the function of real organs....

Among the markers for disease diagnosis or physical understanding using thermal imaging, facial temperatures, which can be measured using a thermal camera, are strongly correlated to mental workload....

Columbia University platform using heavy water as tracer could aid effective removal of tumors. ...

Technique can capture a scene at multiple depths with one shutter click — no zoom lens needed....

NIST researchers demonstrated that laser ranging could "see through flames" to make this image of a plastic skeleton toy. ...

The researchers developed techniques for manufacturing a 256 layer diffraction harmonic lens, as well as the algorithms for reconstructing the obtained images....

VCSELs emit vertically, giving compactness to the laser. They also consume very low energy....

The catheter-delivered imaging tool is said to exploit the dual modality approach by both mapping the shape of blocked blood vessels and identifying the chemical composition of the plaque creating the blockage....

Silicon-based system offers smaller, cheaper alternative to other “broadband” filters; could improve a variety of photonic devices....
