    摘要: A tunable light source for interrogating at least one resonant waveguide grating (RWG) biosensor having a resonance linewidth. The tunable light source includes a broadband light source that emits a light beam having a first spectral bandwidth greater than the RWG biosensor resonance linewidth. The broadband light source may be substantially spatially incoherent. A tunable optical filter having a tunable spectral linewidth is arranged to receive and filter the light beam to cause the light beam to have a second spectral bandwidth substantially the same as the RWG biosensor resonance linewidth. Label-independent optical readers that employ the tunable light source are also disclosed.

    摘要: Disclosed are systems for scoring non-flat materials including non-flat glass sheets (1000). In one embodiment, a laser scoring system is described. The laser scoring system includes a laser (102) and an optical head (106). The optical head (106) is configured to receive output from the laser (102) and focus the output into an elongated laser beam having a beam waist and an extended focal depth of greater than +/−5 mm relative to the center of the beam waist with a power density sufficient for scoring a material having at least a portion within the extended focal depth. In one aspect the system can include a beam expander (104). The beam expander (104) receives the output from the laser (102), expands the output from the laser to an expanded laser beam, and transmits the expanded laser beam to the optical head (106).

    摘要: An optical interrogation system is described herein that can interrogate a label-independent-detection (LID) biosensor and monitor a biological event on top of the biosensor without suffering from problematical parasitic reflections and/or problematical pixelation effects. In one embodiment, the optical interrogation system is capable of interrogating a biosensor and using a low pass filter algorithm to digitally remove problematic parasitic reflections contained in the spectrum of an optical resonance which makes it easier to determine whether or not a biological event occurred on the biosensor. In another embodiment, the optical interrogation system is capable of interrogating a biosensor and using an oversampling/smoothing algorithm to reduce oscillations in the estimated location of an optical resonance caused by the problematical pixelation effect which makes it easier to determine whether or not a biological event occurred on the biosensor.
