    Abstract: To achieve a given spectral resolution with reduced detector size and commercially available pixel pitches, the Raman spectrum is shifted across the detector array such as by one of the following methods: 1) tuning the excitation wavelength; 2) rotating the grating; 3) displacing the effective input slit (fiber) and acquiring the spectrum under stepped displacement conditions; and 4) displacement of a lens relative to input fiber to displace effective input slit relative to the detector. A composite spectrum is formed and deconvolution of the entrance aperture image and/or pixel masking is then used.

    Abstract: A spectrophotometer employs an array of optical elements to focus light from at least one, but preferably two light sources onto a fiber optic beam splitter that provides a pickup for a selected bandwidth of wavelengths of light in the spectral pattern. The spectral pattern can include wavelengths in the visible, near infrared and ultraviolet spectrum. To create the spectral pattern, two reflecting prisms having spherical surfaces are used, and the optical elements are arranged so that the two spectral bands from each prism are longitudinally aligned to create the spectral pattern. The prisms are on a motor driven pivot mount so that the spectral pattern may be swept across the pickup. The optical elements and the pickup are sized so that the selected bandwidth is less than twenty nanometers over the spectral pattern. The pickup is formed by a single row of the ends of fiber optic strands which are then collimated into two bundles to transmit a test component and a reference component of light. The sample cell is somewhat elongated, and a lens is interposed in the test component path before the sample cell, and this lens is sized to focus light axially through the sample cell without impinging on the sidewalls. Photodiode detectors, comparator circuitry and a controller are included.

    Abstract: The invention aims to simplify the design of the known conoscopic measurement devices (10) used for determining the viewing angle-dependent contrast in particular of transmission-operated liquid crystal displays, and to calibrate such a measurement device spectrographically and make it more versatile. This is done according to the invention by dispensing with the conventional projection optics (for forming an image of the interference pattern on a detector array) and making use instead of relatively few individual rapid detectors (18) for spectrally integrating and/or spectrally analysing light measurement. These detectors are connected, directly or as directly as possible via optical waveguide devices (20) in the interference plane to point surface elements in the interference pattern selected according to the angle of view. When optical waveguides (20, 20') which branch off to different detectors are connected, completely different direction-dependent measurements can be made and recorded at precisely the same time and for identical angles of view, as can (in addition to the contrast measurements) saturation measurements and measurements of dynamic switching characteristics.

    Abstract: A scanning-type lithographic and image-pickup device causes the terminal face of either a projecting optical fiber or a picking-up optical fiber to scan a given object in the plane of real image of an objective lens, projects a light through the projecting optical fiber onto the object, and receives the reflected light or a light of photoluminescence through the picking-up optical fiber. When this device is applied to a spectromicroscope, the quantitative surface information can be spectrally measured with high resolution and high reproducibility. When the device is applied to a contracting-projection exposure device or a selective laser annealing device, positional alignment and exposure pattern correction can be easily effected with high accuracy and high productivity. Simultaneous fabrication of a plurality of electronic components can be also obtained by use of this device.
