Abstract:
PROBLEM TO BE SOLVED: To accurately determine a defect dimension and defect coordinates by inspecting a micro defect at high speed without damaging a sample and accurately detecting the amount of scattered light of a large defect. SOLUTION: A plurality of signals with different effective sensitivities are obtained by illumination by a plurality of different illuminance or detection of a plurality of different sensitivities by a pixel, and they are selected and utilized, thereby achieving highly sensitive and wide dynamic range inspection. Further, the plurality of signals are output simultaneously in parallel, and processed, thereby achieving high speed inspection. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
Analyzers and analyzer systems that include an analyzer for determining multiple label species, methods of using the analyzer and analyzer systems to analyze samples, are disclosed herein. The analyzer includes one or more sources of electromagnetic radiation to provide electromagnetic radiation at wavelengths within the excitation bands of one or more fluorophore species to an interrogation space that is translated through the sample to detect the presence or absence of molecules of different target analytes. The analyzer may also include one or more detectors configured to detect electromagnetic radiation emitted from the one or more fluorophore species. The analyzer for determining multiple target molecule species provided herein is useful for diagnostics because the concentration of multiple species of target molecules may be determined in a single sample and with a single system.
Abstract:
A wafer scanning system includes imaging collection optics to reduce the effective spot size. Smaller spot size decreases the number of photons scattered by the surface proportionally to the area of the spot. Air scatter is also reduced. TDI is used to produce a wafer image based on a plurality of image signals integrated over the direction of linear motion of the wafer. An illumination system floods the wafer with light, and the task of creating the spot is allocated to the imaging collection optics.
Abstract:
The present invention is directed to a method and an apparatus for detecting micro-colonies growing on a membrane (1) or an agarose medium of a sample (5) in a closed device (3). According to the invention the sample (5) is irradiated with a light incident at an angle (β) with respect to the normal to the membrane (1) or the surface of the agarose medium from outside the device (3). An incident area (7) of the light on the membrane (1) or the surface of the agarose medium is imaged by means of a light receiving element (9) using an imaging angle (α) different from angle (β) with respect to the normal to the membrane (1) or the surface of the agarose medium from outside the device (3). The light reflected, scattered and/ or diffused from the membrane or the surface of the agarose medium and/or the micro-colonies on the membrane and/or the micro-colonies on the agarose medium is detected.
Abstract:
A detection system based on modulation of line structured laser image of glass comprises processing section (2), control system, and roller conveying mechanisms (5). Detection mechanism (6) provided over entrance of the processing section (201) comprises shell and camera (602) with laser (601) which emits beam on the surface of the glass in the gap between sliding rollers. Focal plane of the camera (602) corresponds to the beam irradiation surface, and signal output terminal of the camera (602) is connected with the control system in such a way that when glass passes the detection area, laser irradiates the glass surface and the line structured laser is modulated based on the glass to form laser modulation image with distribution of light and shade, staggered movement direction, or distorted laser lines. The camera (602) will transmit the captured glass information and parameters to the control system. In the system, the detection mechanism (6), with integral design and compact structure, can be easily fitted over the entrance of the processing section (201), has strong adaptation to other processing means, has no special requirements on incident angle of light and angle of detection surface during detection, and obtains highly accurate data through measurement.
Abstract:
The present invention relates to DNA sequencing with reagent cycling on the wiregrid. The sequencing approach suggested with which allows to use a single fluid with no washing steps. Based on strong optical confinement and of excitation light and of cleavage light, the sequencing reaction can be read-out without washing the surface. Stepwise sequencing is achieved by using nucleotides with optically cleavable blocking moietys. After read-out the built in nucleotide is deblocked by cleavage light through the same substrate. This ensures that only bound nucleotides will be unblocked.
Abstract:
The illumination power density of a multi-spot inspection system is adjusted in response to detecting a large particle in the inspection path of an array of primary illumination spots. At least one low power, secondary illumination spot is located in the inspection path of an array of relatively high power primary illumination spots. Light scattered from the secondary illumination spot is collected and imaged onto one or more detectors without overheating the particle and damaging the wafer. Various embodiments and methods are presented to distinguish light scattered from secondary illumination spots. In response to determining the presence of a large particle in the inspection path of a primary illumination spot, a command is transmitted to an illumination power density attenuator to reduce the illumination power density of the primary illumination spot to a safe level before the primary illumination spot reaches the large particle.
Abstract:
A method and apparatus is disclosed for multi-mode spectral imaging. In one embodiment, the present invention comprises the steps of illuminating an object with a modified illumination profile, producing a reflected, transmitted or fluorescence image of the illuminated object, scanning the object, and re-imaging the reflected, transmitted or fluorescence light after modifying the light's optical state. The present invention preferably works in conjunction with other imaging systems to provide both high-spectral resolution images with lower temporal resolution and multiple image acquisition with high temporal resolution.
