摘要:
An imaging device includes: a plurality of photoelectric conversion devices configured to convert a received light into an electronic signal; a plurality of collector lenses configured to collect a light and to supply the light to the photoelectric conversion devices, the collector lenses being arranged before each of the photoelectric conversion devices; and a fluid lens configured to refract a light and to supply the light to the collector lenses, the fluid lens being arranged before the collector lenses, wherein the fluid lens has a first and second fluids with refractive indices different from each other and an electrode that applies a voltage to the first and second fluids, and the fluid lens changes an interface topology between the fluids in accordance with a voltage to be applied to the electrode and varies a refractive index of a light supplied to each of the plurality of the collector lenses.
摘要:
A light control device and an imaging device suitable for the effective and stabilized driving of a Guest-Host type liquid crystal element. A light control device (23) which is provided with a light controlling GH cell (12) and a UV cut filter (65) provided on the light incident side of the GH cell (12), and which is therefore reduced significantly in the quantity of ultraviolet ray applied to the GH cell (12), thereby preventing the photodecompositon or photodegradation of materials constituting a liquid crystal layer in the GH cell (12); and an imaging device such as a CCD camera (50) having this light control device disposed on the optical path thereof.
摘要:
An optical apparatus having counter electrodes of ITO and working electrodes formed from a conductive paste prepared by dispersing silver or carbon conductive particles in a binder or a sintered material obtained by sintering silver or carbon conductive particles. The counter electrodes can be formed into a structure free of sharp edges which can cause a concentration of electric fields.
摘要:
A digital signal recording and reproducing method and apparatus for digitally recording and reproducing first and second signals in tracks on a magnetic recording includes an encoder and a recording unit. The encoder separately error-correcting encodes the first and second signals of a first and second type, respectively, to produce at least first and second inspection codes corresponding to the first and second signals. The first and second inspection codes have first and second lengths, respectively. The recording unit records the first and second signals and the first and second inspection codes in tracks of the magnetic recording medium so that the first and second signals and the first and second inspection codes are recorded in a track without a gap therebetween.
