Massachusetts Institute of Technology develops optical imaging system ‘DOLPHIN’ for finding tiny tumours

In USA, the researchers at the Massachusetts Institute of Technology (MIT) have developed an imaging system which could be deployed to find tiny tumours, as small as a couple of hundred cells, deep within the body. They used their imaging system, named “DOLPHIN,” which relies on near-infrared light, to track a 0.1-millimetre fluorescent probe through ..

Hyperspectral Imaging Satellite

The Indian Space Research Organisation (ISRO) is planning to launch a full-fledged niche Earth observation (EO) satellite — called the Hyperspectral Imaging Satellite (HySIS). The HySIS satellite has critical chip called an “optical imaging detector array’” indigenously developed by ISRO. ‘Hyspex’ imaging will enable distinct identification of objects, materials or processes on Earth by reading the spectrum ..

What is Spectrum Cap?

The spectrum cap is the limit of radiowaves a telecom operator can hold for providing wireless services. Spectrum cap rules prevent an operator from buying additional spectrum in a respective band. The idea is to prevent operators from acquiring a disproportional amount of spectrum compared to its peers thereby preventing market dominance. As per existing ..
