  • Patent number: 9653108
    Abstract: When recording is performed by focusing a short pulse laser on an inside of a transparent medium such as quartz glass, and forming a minute deformed region in which the refractive index is different from that of surroundings thereof, it is difficult to ensure a recording quality. Therefore, a recorded dot length in a depth direction is monitored 111 and a power of the laser light is adjusted based on the monitored recorded dot length, or a difference between a focus position where a region of the recorded dots appears brighter than the surroundings and a focus position where the region of the recorded dots appears darker than the surroundings is measured and the power of the laser light is adjusted based on the difference.

  • Patent number: 8805038
    Abstract: This algorithm provides a marker-free approach to establishing the pixel correspondence among the IR images taken at different times, which is the basis for quantitatively characterizing the variation of the heat energy and patterns pixel-wise on a breast surface. The idea is to use the corner points of the heat pattern and the branch points of the skeletons of the heat pattern on the body surface as the initial fiducial points for the longitudinal IR image registration. The Thin-Plate Spline technique is used to model the nonlinear deformation between two IR images taken at two different times. Mutual information between the TPS-transformed image and the target image is employed as the metric quantifying the quality of the longitudinal IR image registration. To optimize the registration, Nelder-Mead simplex method is used to locally modify the pairings of the fiducial points in the source and target IR images to maximize the mutual information.

  • Patent number: 7881495
    Abstract: The present invention provides for simple and streamlined boresight correlation of FLIR-to-missile video. Boresight correlation is performed with un-NUCed missile video, which allows boresight correlation and NUC to be performed simultaneously thereby reducing the time required to acquire a target and fire the missile. The current approach uses the motion of the missile seeker for NUCing to produce spatial gradient filtering in the missile image by differencing images as the seeker moves. This compensates DC non-uniformities in the image. A FLIR image is processed with a matching displace and subtract spatial filter constructed based on the tracked scene motion. The FLIR image is resampled to match the missile image resolution, and the two images are preprocessed and correlated using conventional methods. Improved NUC is provided by cross-referencing multiple measurements of each area of the scene as viewed by different pixels in the imager.

Boresight correlation is performed with un-NUCed missile video, which allows boresight correlation and NUC to be performed simultaneously thereby reducing the time required to acquire a target and fire the missile. The current approach uses the motion of the missile seeker for NUCing to produce spatial gradient filtering in the missile image by differencing images as the seeker moves. This compensates DC non-uniformities in the image. A FLIR image is processed with a matching displace and subtract spatial filter constructed based on the tracked scene motion. The FLIR image is resampled to match the missile image resolution, and the two images are preprocessed and correlated using conventional methods. Improved NUC is provided by cross-referencing multiple measurements of each area of the scene as viewed by different pixels in the imager.

  • Patent number: 6819798
    Abstract: A method for determining magnitude and direction of spectral channel drift for several consecutive spectral regions over a wide spectral range. According to the method of the present invention, in-field testing of a spectral filter sequentially irradiated by two blackbody sources is performed to generate a response function of the spectral filter. The response function is ensemble averaged to reduce any noise. Background radiance is then removed to produce a smoothed spectral transmittance function of the spectral filter. The first derivative function of the smoothed spectral transmittance function is determined. The first derivative function is separated into spectral band regions having +/− N pixels on either side of the function minima. The value of N is selected to optimize the detection algorithm sensitivity to change while extending the limit of spectral shift magnitude.

The given medium and immersed tiny metal particles are illuminated through separate phase reference laser beam and sensitive probe laser beam, with the sensitive probe laser beam including a heating laser beam undergoing through impingement on the given medium slight phase changes induced by photothermal effect due to a local heating, in the absence of any substantial phase changes to the phase reference laser beam. Illuminating is performed by focusing the separate phase reference and sensitive probe laser beam through the transparent glass slide at a given depth within the given medium and a transmitted phase reference laser beam and a transmitted sensitive probe laser beam undergoing the slight phase changes are generated.

  • Publication number: 20030104314
    Abstract: An imaging member, such as a negative-working printing plate or on-press cylinder, can be prepared with a hydrophilic imaging layer comprised of a heat-sensitive hydrophilic charged polymer (ionomer) and an infrared radiation sensitive negatively-charged oxonol dye that has a &lgr;max of greater than 700 nm. The heat-sensitive polymer and IR dye can be formulated in water or water-miscible solvents to provide highly thermal sensitive imaging compositions. In the imaging member, the polymer reacts to provide increased hydrophobicity in areas exposed to energy that provides or generates heat. For example, heat can be supplied by laser irradiation in the IR region of the electromagnetic spectrum. The heat-sensitive polymer is considered “switchable” in response to heat, and provides a lithographic image without conventional alkaline processing.

  • Patent number: 6479821
    Abstract: A method, apparatus and system for controlling the amount of heat transferred to a process region (30) of a workpiece (W) from exposure with a pulse of radiation (10), which may be in the form of a scanning beam (B), using a thermally induced phase switch layer (60). The apparatus of the invention is a film stack (6) having an absorber layer (50) deposited atop the workpiece, such as a silicon wafer. A portion of the absorber layer covers the process region. The absorber layer absorbs radiation and converts the absorbed radiation into heat. The phase switch layer is deposited above or below the absorber layer. The phase switch layer may comprise one or more thin film layers, and may include a thermal insulator layer and a phase transition layer. Because they are in close proximity, the portion of the phase switch layer covering the process region has a temperature that is close to the temperature of the process region. The phase of the phase switch layer changes from a first phase (e.g.

  • Publication number: 20020155372
    Abstract: Photothermally sensitive recording sheets for color imaging are disclosed comprising a transparent support sheet having a thermal slip layer disposed on one surface of the support and a heat sensitive image layer on the opposite surface of the support. A second opaque (paper) or transparent (plastic) sheet is laminated to the color-producing layer. The image layer comprises photohardenable microcapsules containing a photopolymerizable or photocrosslinkable compound, a photoinitiator and a dye precursor and a developer material external to the microcapsules. Image-wise exposure of the recording sheet to actinic radiation causes selective photohardening of microcapsules sensitive to that radiation. Heating the resultant exposed recording sheet to a temperature well above the developer melting point by for example a thermal head allows the developer to selectively permeate the non-photohardened capsules resulting in the development of an image, including full color images.
