    Abstract: An optical wide angle sensor head for directionally sensing optical radiation is made of a plurality of individual sensor optical elements. Each sensor optical element is arranged at an input end of its own fiber optical conductor and has its own light entrance, its own field of view and its own individual optical axis. Neighboring fields of view may overlap each other. The fiber optical conductors lead to a transducer for converting the individual light signals into respective electrical signals. The individual sensor optical elements are arranged on a common mounting member in a housing so that the individual optical axes pass through a common intersection in front of said light entrances. The mounting member is a flat plate or a concave plate having a concave curvature facing in the viewing direction, whereby a spherical mounting is avoided.

    Abstract: An optical receiver having a sensory pattern described by a thin cone of apex half-angle 90* (a disc). This is accomplished by means of a cylindrical lens curved in the direction of constant section with a radius equal to the focal length of the lens in the orthogonal plane. A detector is located at the focal point of the lens.

    Abstract: An optical instrument wherein an optical signal is projected on to a sensor array or sensitive medium and angular deflections of the path of the optical signal about an instrument signal source as centre appear as displacements from a datum lying in the general plane of the sensor array or sensitive medium, the instrument having an optical axis passing through said source and normal to said plane, characterized in that, to correct for the tangent law error that would otherwise arise, a correcting optical device is interposed in the signal path and has its surface receiving the signal curved, in the concave sense, about a centre lying on or intersecting the optical axis of the instrument, the curvature being of radius R, where R is greater than the distance t from said instrument signal source to the point in said curved surface that lies on said optical axis, the surface of the correcting optical device facing the sensor array being plane.

    Abstract: A laser detection system for examining a large field of view to determine if the system is being illuminated by laser radiation at a specific frequency. The system includes a first positive lens system for gathering light over a large field of view and for substantially collimating the light for passage through an interference filter. The interference filter allows the passage of radiation in a narrow bandpass region about the specific frequency of laser radiation of interest. Radiation passing through the filter is then condensed by a second positive lens system and directed onto a photosensitive detector. The first and second lens systems form an image of the detector at the entrance to the first positive lens system which defines the entrance aperture to the laser detection system. In the preferred embodiment the first and second positive lens systems each consist of a hyperhemispherical lens and a fresnel lens.

    Abstract: The invention shows a sensor for measuring diffuse solar irradiance including: an hemisphere having an approximately 2π steradian solid opening angle with a non-transparent layer and a transparent aperture pattern, the transparent aperture pattern providing a near-uniform transmission of the diffuse radiation as seen from near a center of the hemisphere, an aperture being an area occupying a part of the hemisphere surface area that is smaller than 2% and two or more light-sensitive sensors arranged in an array near the center of the hemisphere such that under any position of the sun relative to the sensor at least one of the two or more light-sensitive sensors is shaded from direct solar radiation by the hemisphere with aperture pattern.

    Abstract: Provided is a light reduction mechanism which includes a plate-type first beam splitter and a plate-type second beam splitter, in which in a case where the X axis and the Y axis are arbitrary orthogonal coordinate axes in the plane perpendicular to the optical axis of laser beam irradiation optical unit whose origin is in the optical axis, the first beam splitter is arranged with the X axis as a rotation axis and inclined at an angle α in the range from 30° to 60° inclusive with respect to the plane perpendicular to the optical axis, and the second beam splitter is arranged with the X′ axis, which is parallel to the X axis and passes through the optical axis, as a rotation axis, and inclined at an angle −α with respect to the plane perpendicular to the optical axis.
