    Abstract: A mapping-measurement apparatus includes a light illumination unit, a photodetector for detecting, through an aperture, reflection light or transmission light from a sample, and adjustable scanning mirrors on the illumination and detection sides of the sample, each mirror having two independent rotational axes about which they can be independently rotated by a controller. The aperture restricts light incident on the photodetector from a predetermined portion of the sample surface.

    Abstract: A mapping-measurement apparatus for applying mapping measurement to a predetermined area on a surface of a sample, comprising: a light illumination unit for illuminating the sample with light; a photodetector for detecting, through an aperture, reflection light or transmission light coming from the sample; and a detection-side scanning mirror provided in the optical path from the sample to the aperture. The aperture restricts light to be detected by the photodetector only to light coming from a given measurement portion only on the surface of the sample. The detection-side scanning mirror is structured such that the direction of a reflection plane thereof can be changed. The direction of the reflection plane of the detection-side scanning mirror is changed with respect to the incident direction of the reflection light or the transmission light coming from the sample to change the measurement portion on the surface of the sample where measurement is performed by the photodetector.

    Abstract: A precision machine vision inspection system and method for increased inspection throughput. The vision inspection system includes a movable stage for scanning and measuring selected workpiece features. In prior systems, conventional interspersing of image processing and inspection operations with image acquisition operations required stopping and starting the stage motion during image acquisition, necessitating associated delays or wait-states in various operations. Such delays are avoided in this invention by acquiring images continuously, with a timing that is independent of image inspection operations, so that delays and wait-states are avoided. In addition, continuous stage motion is combined with a strobe lighting feature during the image acquisition operations to acquire blur-free images at a high rate. Improved image acquisition and image analysis routines including these features are created and stored by the system.

    Abstract: A laser imaging system is disclosed which provides the versatility of wide field digital imaging with enhanced spatial resolution and light gathering efficiency. The system will scan targets of any size, dependent only upon the data retrieval and storage limitation of the computer support system, for forward light loss densitometry images as well as fluorescent and forward scatter images. The system is easily adaptable for rare event detection and tracking. The laser system will provide image capture of an entire target within 10 to 60 seconds and controls the scan of the laser beam in three-dimensional pattern and speed. The beam may be repositioned to any one of 16 million locations on a target within an accuracy of +/-0.5 um. Finally, the imaging system of the present invention utilizes a novel optical fiber based detector assembly having NA values of 0.58-0.95 and filters having less than 15% loss at emission wavelengths. Thus, the imaging system of the present invention can capture from 14% to 32% of total fluorescence emission.

    Abstract: This invention concerns spectroscopy apparatus comprising a light source arranged to generate a light profile on a sample, a photodetector having at least one photodetector element for detecting characteristic light generated from interaction of the sample with light from the light source, a support for supporting the sample, the support movable relative to the light profile, and a processing unit. The processing unit is arranged to associate a spectral value recorded by the photodetector element at a particular time with a point on the sample predicted to have generated the characteristic light recorded by the photodetector element at the particular time based on relative motion anticipated to have occurred between the support and the light profile.
