摘要： A lithographic apparatus has an illumination system that conditions a beam of radiation. A patterning support supports a patterning device, which serves to impart the beam of radiation with a pattern in its cross-section. A substrate support holds a substrate. A projection system projects the patterned beam of radiation onto a target portion of the substrate. A particle detection system detects a particle on a surface of an object. The particle detection system has a radiation source, which generates an illumination beam of radiation. The illumination beam of radiation is directed along a first optical path to a detection area at the surface of the object. A radiation detector receives a detection beam of radiation from the detection area along a second optical path. The length of the first optical path is made substantially equal to the length of the second optical path.

摘要： A projection device comprises a matrix (1) of semiconductor lasers, an optical system (2) for projecting the matrix (1) on an element (3) illuminated by the projection device, and a control device (9) for controlling the semiconductor lasers through a feedback device. The feedback device comprises a first detector (13, 14) that generates a first signal representing the detected intensity. The semiconductor lasers are controlled and the intensity of the light spot is adjusted to a desired value by the feedback device. Light from a semiconductor laser is detected by a second detector (18), and a value of the detected signal is stored in an addressable memory cell. The amount of emitted light is stabilized for each semiconductor laser by detection through the second detector (18) and comparison with the value stored in the memory (29) for the relevant controlled semiconductor laser.

摘要： An apparatus for reading disc-shaped information carriers which are provided with substantially circular tracks, in which information is stored in coded form, in particular picture information, which information carriers are disposed on a turntable, a read unit supplying a control signal to a control device for maintaining the reading speed constant.The control device comprises at least two mass elements which are connected to the turntable symmetrically relative to the axis of rotation of the turntable, resiliently in the radial direction and rigidly in the tangential direction, which elements are radially movable in response to the control signal.In one control device each element consists of an axially magnetized rod-shaped permanent magnet, which is attached to the turntable by at least one radially flexible leaf spring, a coil being disposed around each magnet, which coil is connected to the control signal.In another control device each element is identically attached to the edge of a metal disc via a connecting rod, which disc is disposed centrally and loosely around the drive shaft of the turntable, at least one electro-magnet being disposed underneath the disc, which electro-magnet magnetically cooperates with the disc and is connected to the control signal.The control signal is to be derived from a pilot signal in the information signal.

摘要： The present invention relates to an analysis apparatus, in particular a spectroscopic analysis apparatus, for analyzing an object, such as blood of a patient, and a corresponding analysis method. To aim the confocal detection volume inside a blood vessel orthogonal polarized spectral imaging (OPSI) is used to locate blood capillaries in the skin. An imaging system (img) with slightly shifted imaging planes (i1, i2) for OPS imaging of blood vessels is proposed to provide auto-focusing. The confocal Raman detection plane (dp) is located in between these two imaging planes (i1, i2). Based on measured amount of defocus for the imaging planes (i1, i2), the focusing of the imaging system (img), the excitation system (exs) for exciting the target region and the detection plane (dp) is located inside the blood vessel (V). Thus, continuous auto-focusing with high accuracy can be achieved. The invention relates also to an optical tracking system for continuously tracking a point of a moving object (obj).

摘要： To enable differentiation between a particle and a ghost particle, a detector system is presented. The detector system is configured to output at least two detector signals corresponding to an intensity of radiation being incident on the detector system. If radiation is received from a ghost particle, not all of the at least two detector signals has a level above a predetermined threshold level, whereas radiation received from a contaminating particle results in all signals having a level above a threshold level. Thus, it may be determined with a high accuracy whether a particle or a ghost particle is redirecting radiation towards the detector system.

摘要： To enable differentiation between a particle and a ghost particle, a detector system resolves radiation from a ghost particle from radiation from an actual particle. The detector system outputs at least two detector signals corresponding to intensities of radiation being incident on different parts of the detector system or the detector system outputs at least two detector signals corresponding to intensities of radiation with different wavelengths being incident on the detector system. If radiation is received from a ghost particle, not each of the at least two detector signals has a level above a predetermined threshold level, whereas radiation received from a particle results in the signals having substantially a same level above a threshold level. The detector system may include a radiation detector device configured to generate the first detector signal in response to radiation incident on at least one predetermined part of the radiation detector device and a radiation blocking assembly configured to prevent radiation not originating from a particle from being incident on the predetermined part of the detector device.
