摘要： A scanning microscope includes a stage for holding a sample, a scan mechanism, a probing system for probing a region of the sample, a position sensor, and a controller. The scan mechanism is configured to translate the stage between at least two axial positions. The probing system includes an optical element and a photosensor having a readout region, where the readout region extends in a direction which is transverse to an ideal orientation of the stage. The position sensor is configured to measure a transverse position of the stage and/or of an orientation of the stage. The controller is configured to adapt the probing system as a function of the measured transverse position and/or the measured orientation.

摘要： An apparatus having a frame (1) carrying a turntable (3) for supporting the information carrier, which turntable is rotatable about an axis of rotation (3A), a slide (9), which is movable between two end positions, with a scanning unit, guide spindles (5, 7) and a linear motor unit (17, 19) for the slide, and an electrically energizable clamping unit (21). In the non-energized condition the clamping unit clamps the slide in any arbitrary stationary position of the slide along its path and in the energized condition it does not clamp the slide. During operation of the device a control unit at least substantially simultaneously turns on a first energizing current to the motor drive unit and a second energizing current to the clamping unit at the beginning of a displacement of the slide and at least substantially simultaneously turns off the first energizing current and the second energizing current at the end of the displacement.

摘要： A control system in accordance with the invention comprises error signal generating means for generating an error signal in response to a reference signal and a first and a second position signal. The reference signal is a measure of the desired value of a position of a first part of a drive system with respect to a second part of the drive system. The position signals are a measure of the actual value of said position. The error signal is a measure of the difference between the desired value and the actual value of the position. The control system further comprises energizing means for energizing a motor which is to be controlled by the control system in dependence on the error signal. The control system of the invention is characterized in that the error signal generating means are adapted to generate weighting factors from the reference signal, for weighting the position signals with the weighting factors and determining a sum of the weighted position signals. The control system can be used in a recording/playback device for positioning a read/write head.

摘要： An optical probe and an optical imaging system include an optical guide, and an actuator having driving coils and a magnet. By supplying a driving current through the driving a magnetic flux is generated which causes a displacement of the distal end of the optical guide. A position measuring device includes a position measuring coil used for monitoring the position of the optical guide, where displacement of the guide distal end causes change in the relative positions of the measuring and driving coils. A power supply supplies a high frequency AC current through the driving coils which causes, an induced voltage in the position measuring coil and thus generates a magnetic coupling between the measuring and driving coils. This induced voltage change is indicative for the position of the distal end.

摘要： A read apparatus for reading a record carrier (1) having a concentric track pattern comprises a scanning device (2, 3) for reading the information, and a separator circuit (4) for extracting a periodic synchronizing signal (Ps) from the information read. By means of a servo system, which inter alia includes a drive motor (9) for driving the disc 1 and a control circuit (5), the rotational speed of the disc is controlled so as to maintain the periodic synchronizing signal (Ps) in synchronism with a reference signal (Pr). The circuit (9a) rejects those signal components in the control signal (U) for the motor (9) which are caused by an eccentric position of the center of rotation of the disc relative to the track pattern. This prevents these signal components from causing an unnecessary dissipation of electric power in the motor, yielding a substantial improvement in motor efficiency.
