摘要： Method for no-contact measurement of the relative velocity, position, or displacement path of objects without special optical markers with respect to a reference position in at least one coordinate direction, or of the degree of image quality of an image wherein the apparatus images the object on a grating and the light fluxes leaving this grating are measured by means of photoelectric elements. The output signals of the photoelectric elements exhibit a frequency component proportional to the velocity of travel. The present invention is distinguished from the prior art by having a physical beam splitter (6,13) inserted in the imaging beam path in front of the grating (5,14), and preferably several polarizing beam splitters (7,30-33) with at least respectively one associated photoelectric receiver pair (10,11,16-19 16'-19') are connected after the grating (5,14).

摘要： A system for determining photoelectrically the position of at least one focus plane of an image within an optical apparatus, wherein the object is reproduced at least at one spatial frequency filter of an optical image correlator and there is measurement and/or display of the light fluxes leaving the local frequency filter.In this system light fluxes traversing differing pupil sections of the reproducing optics are modulated in common by a spatial frequency filter and are split up geometrically or physically, or by means of additional modulation in correspondence with the pupil sections. They are consecutively or simultaneously projected on a common photoelectric receiver or on separate photoelectric receivers, the output signals of which are processed further for purposes of controlling display and/or follow-up devices.

摘要： System for monitoring spaces by electro-optical means, using optical imaging means (1) capable of detecting objects present in the monitored spaces and beam splitting means (2) for grating resolution of the object images into geometric, mutually complementary components. The imaging and beam splitting means form a correlation imaging sensor system equipped with photoelectric detectors (4,5) for the purpose of separately converging light fluxes corresponding to the image components into analogue electrical signals, and electrical means for measuring the amplitudes and phases of the signals as well as their variations. The correlation sensor system analyzes these values with respect to presence and/or motion of objects within the monitored spaces.

摘要： Polar structures in microscopic object areas, such as, for example, electric or magnetic dipoles, can be locally selectively detected with high resolution if either resonant ultrasonic waves are induced in the object area by a locally effective high-frequency field and are detected by means of a focused acoustic lens arrangement, or electric or magnetic high-frequency oscillations are induced in the object area by focused ultrasonic waves and are detected by an appropriate receiver. By comparing the phases and/or amplitudes of the induced and of the detected waves, these provide information on the existence and the direction of the dipoles. Existing dipole alignments can be made energetically unstable by a critical direct-current electric or magnetic field and locally selectively reversed by the focused ultrasonic beam.

摘要： The exposure meter is used in mirror reflex cameras wherein an image of an object projected by a picture taking lens onto an image plane is observed by means of a pentaprism through an ocular. For the purpose of the selective integral or spot exposure metering, a pentaprism (6) is provided at the lower edge of its exit surface with a partly transmitting concave mirror (16). The angles of the pentaprism (6) are selected so that a portion of the light flux leaving the exit pupil (EP) of the picture-taking lens (2) is incident on this concave mirror (16). A first photoelectric detector system is associated with the concave mirror (16) and a second detector system is associated with the prism surface (6c) following the concave mirror in the direction of the beam path, and the output signals from these detectors control a display and/or an exposure control. An additional optical component (13,14a,15b,15) is provided to implement a desired beam path in the pentaprism (6).

摘要： An acoustic scanning microscope uses damping of a resonant acoustic oscillator and an acoustic near-field effect. In a preferred embodiment, a 32 KHz tuning fork serving as an acoustic oscillator with a 50 nm point achieves a vertical resolution of 5 nm and a horizontal resolution of 50 nm in the case of a minimum distance of approximately 50 nm. Frequency or amplitude variation of the resonant acoustic oscillator can be used. The acoustic near-field effect is dependent on the coupling medium, e.g., air, and the pressure, e.g., normal pressure.
