Optical Phantom

Jul 2010
INO - National Optics InstituteRequest Info
INO has launched the BioMimic optical phantom, which replicates the optical properties of human and animal tissue. Based on optical-quality polymers, the solid phantom incorporates visible and near-infrared absorbing dyes and TiO2 scatterers to re-create a variety of tissues. It is suitable for systems calibration, and its applications include Monte Carlo simulation, absorbance and scattering property determination, time-resolved fluorescence measurement and fluorescence spectral calibration.

The natural log of the ratio of absorbed intensity over the total intensity which gives a constant value assuming a stable volume as well as energy. In optical physics the absorbance may be defined as the absorption cross section multiplied by the absorbing material length.
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
Monte Carlo simulation
Simulation of radiative transfer in which each photon is generated by a source and its path through the medium is statistically simulated with absorption and scattering probabilities as well as with probabilities associated with angular dependence of scattering. Monte Carlo simulations are based purely off of the random sampling techniques associated with statistics and probability and are applied when trying to model phenomena of uncertainty. In radiative transfer, this uncertainty being the...
A material whose molecular structure consists of long chains made up by the repetition of many (usually thousands) of similar groups of atoms.
