The ESA monitor's operation is based on beta radiation attenuation technology while the Sigrist monitor operation is based on optical light scattering technology.
Diffuse optical spectroscopy (DOS) of breast tissue provides quantitative, functional information based on optical absorption and scattering properties that cannot be obtained with other radiographic methods.
We used an HHPC-6 hand-held particle counter (ART Instruments, Grants Pass, OR) to determine the airborne particle number concentration based on optical counting principles using laser light scattering.
Based on optical transformation, we proposed a camouflage coating, which can camouflage an arbitrary object by mimicking electromagnetic scattering of an empty v-shaped cavity under a metallic ground plane.
Optical biosensors are usually made based on optical diffraction.
The measurement principle of LM10 is based on optical triangulation.
Based on Mie optical scattering theory, imaging through blood using infrared light was theoretically feasible, but scattering in the near-infrared wavelengths (1100 to 1300 nm) generated substantial noise in the image despite relatively low absorption.
Based on the optical scattering as its contrast mechanism, OCT has been demonstrated from its outset as a label free imaging tool (i.e., Doppler OCT) to image and monitor dynamic blood flow within tissue beds in vivo.
Optical tomograms were collected on a population of 30 biopsy-confirmed lesions (i.e., the training set), and logistic regression was used to generate an optimized weighting vector for computation of tissue probability of malignancy based on optically measured total hemoglobin concentration, blood oxygen saturation, and reduced scattering coefficient [ 11].
In the middle of these two particular scattering properties, suppressed backward scattering and enhanced directional forward scattering are typically of more practical application, such as in optical antennas [15 17], plasmon-enhanced photovoltaics [18, 19], and other devices based on optically induced "negative forces" [20].
