Photometry Definition & Meaning Dictionary.com

WebPhotometry is the science of the measurement of light, in terms of its perceived brightness to the human eye. It is distinct from radiometry, which is the science of measurement of radiant energy (including light) in terms of absolute power. In modern photometry, the radiant power at each wavelength is weighted by a luminosity function that models … Fiber photometry is a calcium imaging technique that captures 'bulk' or population-level calcium (Ca ) activity from specific cell-types within a brain region or functional network in order to study neural circuits Population-level calcium activity can be correlated with behavioral tasks, such as spatial learning, memory recall and goal-directed behaviors. The technique involves the surgical implantation of fiber optics into the brains of living animals. The benefits to researchers are that … chuck roast in crock pot for tacosPhotometric stereo is a technique in computer vision for estimating the surface normals of objects by observing that object under different lighting conditions.
