Sometimes, different organisms can evolve the same ability independently, a process called parallel evolution. A new study ...

A new field study shows that combining multiple optical signals can reveal not only how much carbon a semiarid grassland ...

Recently the public has become aware of the potential of light field photography through the introduction of the Lytro camera. Light field recording allows an enormous degree of post-processing, ...

The study suggests that physically informed AI can do more than interpolate missing data; it can help connect satellite ...

An image printed on reflectance paper responds to the direction from which it is illuminated. The reflectance paper is covered with dimples that reflect light from different directions. See video ...

Reflectance Medical, its device uses light -- specifically, near infrared spectroscopy -- to read patients’ blood chemistry without cutting into them, will help save the lives of soldiers wounded in ...

A project at the University of Arizona has designed an endoscope intended to assist early detection of ovarian cancer. Described in Biophotonics Discovery, the project's goal was a submillimeter ...

The Earth's albedo, or reflectance, is a fundamental atmospheric parameter having deep implications for temperature and climate change. For that reason, experiments have been performed to monitor it ...

One of the most popular techniques for material identification is single bounce ATR spectroscopy. However, in some cases, the specular reflectance sampling technique may still be necessary. Much like ...
