The movement of carbon between the atmosphere, oceans and continents — the carbon cycle — is a fundamental process that regulates Earth’s climate. Some factors, like volcanic eruptions or human activity, emit carbon dioxide into the atmosphere. Others, such as forests and oceans, absorb that CO2. In a well-regulated system, the right amount of CO2 ...

UCLA researchers led by Aydogan Ozcan and Mona Jarrahi have developed a multispectral imaging technology capable of turning a monochrome sensor into a multispectral one. Rather than the traditional absorptive filters used for multispectral imaging, the technology uses a diffractive optical network to form 16 unique spectral bands periodically repeating at the output image field ...
