Abstract: A device for the photoelectric measuring of an opaque or transparent object to be measured includes a photoelectric sensor (4) and a measuring optics (3) which directs measuring light originating from a measurement field of the object to be measured (6) onto the sensor (4). A control electronic (5) cooperates with the sensor (4) for the processing of the electrical signals produced by the sensor. The sensor (4) includes at least two individually controlled and concentrically arranged partial sensors (41, 42, 43), and the control electronics (5) includes switching means (51) by which the partial sensors (41, 42, 43) can be selectively switched on or off-line. The use of a photoelectric sensor made of or divided into several partial sensors enables a purely electronic and therefore simple and fast selection of different effective measurement field sizes.

Abstract: A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(mnullnullpnull/4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by correspond filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

Abstract: A postacquired spectrophotometer, for use with a sample and reference. The spectrophotometer has a filter unit, defining an axis of movement, and pluralities of designated sites and dark sites disposed in uniform relation to the axis. The designated and dark sites are disposed in alternation. Alternating designated sites have apertures and filters covering the apertures. Further, a main member, coaxial with the filter unit, has sample and reference beam paths, which are intersected by the sites. The main member has disposed, in operative relation to the actuators, an actuator sensor, which generates an integration actuator signal upon alignment with each integration actuator and a clamping actuator signal upon alignment with each clamping actuator. Moreover, a drive continuously moves the filter unit relative to the axis and beam paths. Further, a light distribution system directs light separately from the sample and reference to respective beam paths, and then to a detector, which produces a detector signal responsive to light received. Finally, means for processing the signals is provided, including a clamping circuit, integrators, and a demultiplexer.

Abstract: A microscopic spectrometer having a separate optical path for masking light from a sample for spectrometric measurements. In the preferred embodiment, a beam splitter is disposed behind an object lens to form two branched optical paths. One of the optical paths is provided with masks at a point of focus along the path, allowing part of the image to be masked. The second optical path allows optical throughput and observation of the entire image. These two optical paths are rejoined, and a final image is obtained for visual inspection by synthesizing the two optical paths.

Abstract: This invention relates to a dispersive holographic spectrometer (12) for analyzing radiation from an infrared source (16). The holographic spectrometer (12) comprises a piezoelectric block (40) having a holographic lens (38) on one face, an array of detectors (36) on another face and a pair of vernier electrodes (32, 34) on opposite faces. Radiation from the source (16) incident upon the holographic lens (38) is dispersed into component wavelengths (44, 46) and directed towards the detector array (38). The holographic lens (36) has a holographic interference pattern recorded on it such that radiation of predetermined wavelength components are dispersed sufficiently enough such that radiation of specific wavelengths falls on different detector elements (48) of the detector array (36). By applying a voltage to the electrodes (32, 38), an electric field is created within the piezoelectric block (40) such that it is either compressed or expanded. This change in the piezoelectric block (40) alters the direction of the radiation from the holographic lens (38) to the detector array (36). Therefore, misalignment of the source (16) with the holographic lens (38) can be compensated for such that piezoelectric adjustment of the block (40) will make the radiation of individual wavelengths fall on the desired detector element (48). Further, radiation from different wavelengths can be directed from one detector element to another. The detector array (36) is self-scanning such that an absorption spectrum can be measured and recorded over a range of frequencies.

Abstract: On a measuring table (1), a bridge (2) extends over a printed sheet (5) to be measured. A measuring carriage (3) carrying a three color-simultaneous measuring head is arranged on the bridge (2) for linear movement in a back-and-forth manner along a desired path on the printed sheet. For control of the movement of the measuring head during measuring runs and for the evaluation of the measured data, a computer (7) with an integrated image display terminal and a processor system (6) controlled by the computer, is provided with the necessary interfaces. The analysis of a color measuring strip (MS) located along the desired path on the printed sheet is effected in two phases. In a first, so-called recognition run the measuring strip is scanned stepwise with high resolution in all three color channels, for the purpose of an analysis of its configuration. By means of flat locations in the density variations, effective positions (e.g., the centers) in the measuring fields are determined as possible measuring positions for subsequent measuring runs. During the measuring runs the measuring strip is measured only at the measuring positions determined during the recognition and the measured data obtained in this manner are transmitted for processing and/or display to the computer (7). By the division of the measurements into a recognition and a measuring run, coupled with the determination of measuring positions by means of flat locations in the density variations, a practically completely automatic evaluation of the color measuring strips independently of their configuration and without the need of prior knowledge of the strips by the apparatus, is rendered possible.

Abstract: An apparatus includes a substrate and an optically powered surface. The substrate is transmissive of electromagnetic energy, and includes a plurality of reflective portions oriented and positioned to control a propagation direction of electromagnetic energy along an optical path of the substrate. The substrate further includes an input surface aligned with the optical path so as to allow electromagnetic energy to enter the substrate through the input surface. The optically powered surface is positioned relative to the substrate so as to redirect a field of view of the substrate. The field of view of the substrate is bounded by a first angular width, a field of view of the optically powered surface is bounded by a second angular width, and the second angular width is different than the first angular width.

Abstract: Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.
