    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.

    摘要: An optical reader system is described herein that uses a scanned optical beam to interrogate a biosensor to determine if a biomolecular binding event occurred on a surface of the biosensor. In one embodiment, the optical reader system includes a light source, a detector and a processor (e.g., computer, DSP). The light source outputs an optical beam which is scanned across a moving biosensor and while this is happening the detector collects the optical beam which is reflected from the biosensor. The computer processes the collected optical beam and records the resulting raw spectral or angle data which is a function of a position (and possibly time) on the biosensor. The processor can then analyze the raw data to create a spatial map of resonant wavelength (peak position) or resonant angle which indicates whether or not a biomolecular binding event occurred on the biosensor. Several other uses of the raw data are also described herein.

    摘要: A typical use of linear or two dimensional spectrometers is to expose the detector area, and then shift the photo-electric charges out of the device in a serial fashion. If the illuminating signal is spatially narrow relative to the size of the array, this will drive down the percent of the detector that is utilized, as only a relatively small number of pixels are used to detect the beam. The present invention proposes a method which capitalizes on this spatial under-utilization, and alters the clocking scheme to maximize the read-out speed of the pixels containing signal information. This type of clocking scheme raises the optical power saturation level of the spectrometer. Such an improvement in optical power handling is beneficial for spectrometer based detection of resonant waveguide grating biochemical binding, since in such systems the performance is frequently limited by spectrometer saturation.
