Abstract: A method and system for measuring signal loss in a fiber optic cable. The tail ends of reference and test fiber optic cables are illuminated with a diffuse light. The head end of each of the reference and test fiber optic cables are positioned in a measurement area. A core imager captures an image of the core of each head-end while it is in the measurement area. Reference and test radiant fluxes emitted from the reference and test head-ends are determined from the respective core images. The relative signal loss of the test fiber optic cable is then determined by comparing the test radiant flux to the reference radiant flux.

Abstract: A method, system, and computer program product for determining a core-to-ferrule offset of a ferrule for a fiber optic connector. A reference ferrule is physically aligned with a core imager by positioning the reference ferrule so that edges of the reference ferrule in a plurality of profile images are aligned with fiducial markers in the images. The reference ferrule is incrementally rotated about its longitudinal center access, a core image captured at each rotational angle, and a reference core-to-ferrule offset determined based on the core images. A test ferrule is physically aligned with the core imager by positioning the test ferrule so that edges of the test ferule are aligned with the edges of the reference ferrule in a plurality of profile images. The core-to-ferrule offset of the test ferrule is then determined based on an offset between the test and reference cores in a composite core image.

Abstract: The present invention relates to a laser cutting technology for cutting and separating thin substrates of transparent materials, for example to cutting of display glass compositions mainly used for production of Thin Film Transistors (TFT) devices. The described laser process can be used to make straight cuts, for example at a speed of >0.25 m/sec, to cut sharp radii outer corners (<1 mm), and to create arbitrary curved shapes including forming interior holes and slots. A method of laser processing an alkaline earth boro-aluminosilicate glass composite workpiece includes focusing a pulsed laser beam into a focal line. The pulsed laser produces pulse bursts with 5-20 pulses per pulse burst and pulse burst energy of 300-600 micro Joules per burst. The focal line is directed into the glass composite workpiece, generating induced absorption within the material.

The coating process is controlled to obtain a consistent overflow onto major surfaces of the stacked substrates.

Abstract: A wavelength-tunable detector for use in a label-independent optical reader for reading at least one resonant waveguide grating (RWG) biosensor is disclosed. The wavelength-tunable detector includes a tunable wavelength filter. Broadband light is made incident upon the RWG biosensor to produce resonantly reflected light, which is then passed through the tunable wavelength filter whose central wavelength is adjusted, such as by varying the filter angle of the tunable wavelength filter. This generates filtered resonantly reflected light, which is detected by a photodetector that generates an electrical signal in response thereto. The electrical signal is representative of the detected spectrum, which includes the center resonant wavelength of the RWG biosensor. A controller can be used to determine the center resonant wavelength from the electrical signal.
