摘要： The invention relates to a device (14) for modulating the intensity of a light bundle (12) which is incident in the entrance of a modulator (50). Said modulator can be regulated between two states by means of a control signal (54). In the first state, a minimum proportion of the light bundle (12) leaves an exit of the modulator and in the second state a maximum proportion of the light bundle leaves said modulator. According to the invention, the device (14) has two or more modulators (50, 50', 50'') arranged in a series, so that each light bundle leaving one of the modulators (50, 50') is guided into the entrance of one of the next modulators arranged in the direction of light propagation. After the intensity of the light bundle (16) has been modulated by the device, said light bundle can be removed from the last of the series of modulators (50) arranged in this way in such a manner that the extinction of the device (14) in relation to each of the individual modulators (50) is improved.

摘要： The invention relates to a golf ball, designed in several parts, which has a core (1), a case (2) and a shell (3) and also fulfils the requirements for long distance and provides sufficient spin when the core (1) cannot be deformed or only extremely slightly. Said core (1) of the golf ball therefore consists of an extremely energy-resilient material which can only be deformed slightly and has a modulus of elasticity of ≥ 3 GPa at room temperature. An extremely entropy-resilient elastomer which can be deformed to a high extent, has a modulus of elasticity of ≤ 50 MPa at room temperature, a glass transition temperature of ≤ 0° Celsius and a mechanical loss factor tan δ ≤ 0.2 in a frequency range of up to 1 kHz at room temperature is provided for the case (2) which is ≥ 2 mm thick.

摘要： The invention relates to a process and a device for detecting physical, chemical, biological or biochemical reactions and interactions on plate-like sample carriers with a biochemical or chemical function, on the basis of spectral reflection after the samples (11) have been exposed to light of different wavelengths. It is intended to determine parameters on the properties of the samples (11) with ease, in a very precise manner and with a high degree of parallelisation of the measurements. According to the process, the samples (11) are arranged on a substrate plate (12) with a carrier layer of a support plate (13) and are exposed to rays of light. The process has the following steps: a laminar arrangement of samples (11) to be analysed undergoes illumination, with temporary resolution, with light of different wavelengths of a variable light source (1) or a scanning monochromator (3) which is arranged downstream of a polychromatic light source (1); the ray portion reflected on at least one boundary surface of each sample (11) or the ray portions or interferences interfering and reflected on peripheries of each samples (11) positioned downstream of one another towards the light is displayed by optical elements on a laminar detector array (8) with high-sensitive resolution or a video camera; the wavelengths of the reflected ray intensities caused by the samples (11) or the intensities of the displayed interferences are selectively detected, a wavelength spectrum associated with each sample is determined, and parameters are derived which characterise the interactions and reactions to be analysed.

摘要： In a process for correcting pyramidal errors due to misinclination of facet surfaces of a rotating polygonal mirror (8) that receives light and is used to deflect a beam of light, wherein a misinclination of a facet surface prompts a corrective deflection of the light beam (5) reflected by the specific facet surface (12), at a correction angle opposite to the deflection by misinclination, the invention provides a continuous check on the orientation of the facet surfaces (16) as they pass a measuring point (15), a measure of the angle of misinclination when it occurs and an adjustment of twice the measure as angle of correction of the corrective deflection. A device for carrying out the process has a light-exposed rotating polygonal mirror (8) as well as a deflection device (9, 10) for corrective deflection of the light beam (5) in the event of a misinclination of facet surfaces and a control device which is used to drive the deflection device. With a measuring device (13) the orientation of each facet surface (16) can be continuously monitored with each pass of the measuring point (15), the angle of misinclination can be determined when it occurs and, as a function thereof, an input signal can be sent to the control device (36).

摘要： The invention concerns a video projection apparatus for displaying on a screen (7) a video image composed of pixels of a defined size, with at least one light source (1) for transmitting a light beam (2) having a predetermined beam profile in order to illuminate each pixel on the screen for a predetermined time interval. According to the invention, the beam profile of the light beam (2) is extended further than the defined size of the particular pixel to be illuminated, and the time interval is so short that the size can be perceived in the eye of an observer watching the video image such that it corresponds to the defined size of the pixel. A method in which a video image is composed from pixels on a screen (7) by directing onto the screen (7) a light beam (2) having a predetermined beam profile for illuminating each pixel of a defined size for a predetermined time interval is characterized in that a light beam (2) is used which has a beam profile which is extended further than the defined size of the particular pixel to be illuminated, and each pixel is illuminated for such a short time interval that the size is perceived in the eye of an observer watching the video image such that it corresponds to the defined size of this pixel.
