Abstract: The imaging apparatus and endoscope apparatus comprise an image forming optical system forming the image of an object to be imaged. An imaging device has a sensitivity to a wavelength range ranging from a visible range to a range other than the visible range and converts the image formed by the image forming optical system to an electric signal. A wavelength range divides device dividing the wavelength range ranging from the visible range to the range other than the visible range into a plurality of wavelength ranges. A selects device selecting at least one wavelength range from among the wavelength ranges divided by the wavelength range dividing device. A signal processing device processes the output signals of the imaging device in response to the selected wavelength ranges so as to be video signals.

Abstract: An optical analysis system employs a rectangular beam of light passing through interference filters to analyze the constituents of a test sample moving through the beam. A plurality of interference filters are moved successively through the beam between the source of the beam and the sample and are tilted about an axis as they are moved, thereby transmitting a range of wavelengths to the sample. Skew rays of light in the beam strike the filters at different angles from the angles at which rays parallel to the axis of the beam strike the filters and so transmit wavelengths different from those of rays parallel to the axis of the beam. The angle deviation is greatest for the skew light rays which are skewed from the axis of the beam in a plane perpendicular to the tilt axis of the filters. Thus, the shorter dimension of the rectangular beam is arranged to be perpendicular to the tilt axis of the filters.

Abstract: System in which multispectral filtering and variable optical attenuation are effected on the same support. In the case of a supporting disc it has two angular graduated attenuators produced symmetrically with respect to a referenced diameter. Each attenuator also forms optical filters in a given spectral band so as to be able to operate in two separate bands. The disc is positioned in the vicinity of a relay objective positioned between the receiving objective and the opto-electrical transducer. The detected signal supplies a loop controlling the angular position of the disc. The disc is controlled in such a way that the switching of the band takes place on passing through the maximum density zones of the attenuators.

Abstract: This monochromator is made up of a number of discrete narrow band interference filters mounted on a drum which rotates with respect to a light beam so that as the light beam passes through each of the filter the angle of incidence of the light beam changes with respect to the filter. Each of the filters is for a different normal wavelength of peak transmission so that spectral analysis of the light source can be obtained.

Abstract: A scanner having an instantaneous narrow field of view determines spectral and positional information of a point source of optical radiation in a relatively wide field of view. A first optical path includes the scanning means, a dispersion means, and a first detector means so that different wavelengths of the source are convoluted to impinge on the first detector means at different times during a scan of the field of view. A second optical path includes the scanning means, the second detector means, and a narrow bandpass filter for enabling approximately monochromatic energy of the source to impinge on a second detector means displaced from the first detector means. Thereby, a predetermined wavelength is imaged on the second detector means at a time during a scan that differs from the time when that wavelength is imaged on the first detector means, even though the source angular position in the field of view is substantially the same for both of the optical paths. To enable the system to be responsive only to point sources, to the exclusion of nonpoint sources, each of the first and second detector means is divided into a multiplicity of separate, spaced detector elements. Each of the detector elements has a length in the direction of scan no greater than the length of the point source imaged on the first and second detector means. In response to the amplitude of energy impinging on the elements of the second detector means, a signal replica of the convoluted spectral energy impinging on one of the elements of the first detector means is coupled to a signal processing network that recognizes point sources having a predetermined spectral signature and enables the position of the recognized sources to be determined.
