    Abstract: A magnetic film includes one or more magnetically conductive layers. Each magnetically conductive layer is cracked to form a plurality of first through-cracks defining a plurality of magnetically conductive segments. The first through-cracks extend along a first direction and form a first regular pattern along an orthogonal second direction at a first pitch P1, such that a Fourier transform of the first regular pattern has a first peak along the second direction at a first spatial frequency corresponding to the first pitch P1. The first through-cracks have an average length L1 along the first direction. L1/P1 is greater than or equal to 5.

  • Patent number: 7057806
    Abstract: An enhanced resolution scanned image of an object is produced by a scanning laser microscope which includes an illumination arm for scanning an object with a focused probe beam and a detection arm for receiving light from the object. The detection arm includes a detector which collects and detects light from the object to produce pixel data for a plurality of pixels. In addition, the detection arm includes a wavefront sensor for sensing phase variations of the light from the object to produce wavefront data for scanned pixel locations. From the wavefront shape of the collected light at each pixel location, a high frequency spectrum is determined which corresponds to uncollected scattered light from small scale features of that pixel location. An enhanced resolution image of a region of interest is produced based on the high frequency spectra of the scanned pixel locations.

  • Patent number: 6717124
    Abstract: The present invention provides for very rapid autofocusing of optical scanning systems. If a sample is sufficiently out of focus, the focal error signal used to focus a conventional half-blocked system can become saturated. Multiple steps toward the focus position then typically are required to bring the system into the operational range. To minimize this, a light adjustment system is provided to reduce the amount of light impinging on the half-blocked system when the focal error signal is at or near saturation. The half-blocked system then becomes primary controller again, and can move the system into a position generally close to the correct focal point. The light adjustment system then can be deactivated, but since the system now is much closer to focus, the half-blocked system can quickly bring the system into final focus. Alternatively, the photodetectors used to generate the focal error signal are segmented.

  • Patent number: 6108127
    Abstract: A confocal scanning microscope includes a light source which provides a light beam and scanning optics which sweep the light beam across the surface of a sample. Light from the surface or interior of the sample passes through a pinhole lens which focuses the light on a pinhole for detection by an optical detector. An image of the surface may be scanned using the optical detector. An optical element is inserted in a detection arm of the confocal microscope. The optical element provides angular magnification and natural divergence to the beam from the surface of the sample.
