  • Patent number: 8564773
    Abstract: In a spectroscopy module 1, a light passing hole 50 through which a light L1 advancing to a spectroscopic portion 4 passes is formed in a light detecting element 5. Therefore, it is possible to prevent the relative positional relationship between the light passing hole 50 and a light detecting portion 5a of the light detecting element 5 from deviating. Moreover, the light detecting element 5 is bonded to a front plane 2a of a substrate 2 with an optical resin adhesive 63. Thus, it is possible to reduce a stress generated onto the light detecting element 5 due to a thermal expansion difference between the light detecting element 5 and the substrate 2. Additionally, on the light detecting element 5, a first convex portion 101 is formed so as to be located at least between the light detecting portion 5a and the light passing hole 50 when viewed from a direction substantially perpendicular to the front plane 2a.

  • Patent number: 8564778
    Abstract: A spectrophotometer 300, webcam 302 or other instrument measures the color composition and texture of a person's face 400 or other body part. A computer system 301 includes a processor 501 and a non-transitory, non-signal computer readable medium 500 containing machine readable instructions that accept data from a spectrophotometer 300 or like instrument and uses a main executable program 502 and a subroutine 504 for color analysis to derive a mix of color to create a cosmetic product matching or enhancing the color composition and/or texture of the person's face or other body part. The computer system 301 and subroutine for color analysis create machine readable instructions 505 for the firmware of a cosmetic blending and dispensing machine 508. In order to properly mix and dispense high viscosity and air bubble riddled cosmetic material, a medical grade peristaltic pump 354 is used with triangle needle nozzles 374.

  • Patent number: 8558998
    Abstract: Methods and systems are disclosed of sensing an object. A first radiation is spatially modulated to generate a structured second radiation. The object is illuminated with the structured second radiation such that the object produces a third radiation in response. Apart from any spatially dependent delay, a time variation of the third radiation is spatially independent. With a single-element detector, a portion of the third radiation is detected from locations on the object simultaneously. At least one characteristic of a sinusoidal spatial Fourier-transform component of the object is estimated from a time-varying signal from the detected portion of the third radiation.

  • Patent number: 8559008
    Abstract: An ellipsometer includes an integrated focusing system with a beam splitter between the sample and the ellipsometer detector. The beam splitter provides a portion of the radiation to a lens system that magnifies any deviation from a best focus position by at least 2×. The focusing system includes a 2D sensor, where the spot of light focused on the sensor is 50 percent or smaller than the sensor. The focusing system may further include a compensator to correct optical aberrations caused by the beam splitter. A processor receives an image signal and finds the location of the spot from which focus error can be determined and used to correct the focal position of the ellipsometer. The processor compensates for movement of the spot caused by rotating optics. Additionally, a proportional-integral-derivative controller may be used to control exposure time and/or gain of the camera.

  • Patent number: 8553224
    Abstract: Optical fibers are utilized to provide high efficiency, spatially resolved coupling of light from collection optics to an imaging spectrometer. In particular, a micro lens array may be utilized to couple light from multiple spatial locations into individual optical fibers. At the opposite end of the fiber bundle, the fibers are packed tightly together to send the light into an imaging spectrograph. The light that enters this spectrograph maintains its spatial separation, for instance, along the array dimension and is spectrally dispersed, for instance, along a dimension orthogonal to the array dimension. This spatially separated, wavelength resolved light can then be recorded on a two dimensional detector such as a CCD camera.

  • Patent number: 8547536
    Abstract: The quality control of vaccines is an important step in the release of vaccines to patients. Problems when dealing with vaccines include stability, batch-to-batch consistency and contamination. The invention provides a method of analyzing the composition of a protein-containing sample by electromagnetic spectroscopy, and derivatizing the obtained spectrum to obtain a derivative spectrum of the sample. The derivative spectrum may optionally be compared to a reference spectrum, to assess stability, contamination etc. relative to the reference. The derivative analysis technique allows the separation and discrimination between the spectral contributions of different components, thereby allowing differences in the spectra to be assigned to particular groups of the protein, or particular contaminants etc.

  • Patent number: 8525987
    Abstract: A method for operating an optical filter in multiple modes. In one embodiment, an optical filter may be operated in a sensitivity mode to thereby generate a white light image representative of a region of interest. The optical filter may then be operated in a specificity mode to thereby generate a hyperspectral image representative of said region of interest. The white light image and the hyperspectral image may be fused to generate a hybrid image that provides morphological and hyperspectral data. The white light image and the hyperspectral image may be generated using a single detector, eliminating the need for image realignment.
