As an example, the crystalline phase of an optical recording material has low thermal conductivity but high electrical conductivity, simultaneously.
In the eighteen-eighties, for instance, the Volta Laboratory, led by Bell, developed a type of photographic disk that contained an optical recording and was played back by light, forty years before the same technique was adapted for movie soundtracks.
The employment of an optical recording system allowed for a direct and objective assessment of visible piloerection.
Continuous assessment of piloerection was carried out by means of an optical recording device, which captured video data from the unilaterally illuminated skin surface (Benedek et al., 2010).
Changes in light absorption associated with membrane potential changes were measured using an optical recording system equipped with a high-speed diode camera with metal oxide (MOS) image sensors (128 × 128 pixels, each of which receives light from a 25 μm × 25 μm sample area) and a data processing unit (HR Deltaron-1700 Fujix; Fuji Photo Film, Tokyo, Japan).
A system for holographic interferometry using bacteriorhodopsin films as an erasable optical recording medium is presented.
A new optical recording channel has been developed that supports unsaturated, M-ary (M≥3) signal levels.
During simulation, a Gaussian optical recording channel was assumed with impulse response given by (17).
At the same time, an external surrogate (e.g., an optical marker) records the amplitude of respiration.
Here, a five-dimensional optical recording technique using polarization of light and its wavelength as the two additional dimensions, is demonstrated.
