The ROC analysis is based on optical density values.
"Nearly all of today's telecommunication is based on optical networks," and biotechnology is highly dependent on optical technologies as well, such as microscopy, he points out.
The doubling time of the exponentially growing cultures was then calculated based on optical density measurements.
Optical biosensors are usually made based on optical diffraction.
The measurement principle of LM10 is based on optical triangulation.
Science is based on facts, so science and science-related fields probably attract more thinkers ( Ts).
Optical techniques based on intrinsic optical contrast (such as diffuse optical tomography) can provide spectroscopic information about physiological and functional tissue parameters (for instance, tissue oxygenation) [ 3, 4].
Some are based on very questionable science, or no science.
B.D.J.: Science fiction based on science fact gives us a language to talk about the future.
