    摘要： A test system includes an optical medium, a binding agent capable of capturing a target complex, and a light detector. The optical medium provides a light path, and the binding agent is positioned to hold the target complex in an evanescent field created by propagation of light along the light path. The complex interacts with the evanescent field and emits light that the detector positioned to detect. The optical medium and the detector can be included in an optical integrated circuit where detected light passes through the optical medium transverse to the direction of the light path.

    摘要： A ferroelectric liquid crystal-based switchable half-wave plate with improved alignment control, a ferroelectric liquid crystal-based light valve system with improved contrast control, and a method of improving contrast in a ferroelectric liquid crystal-based light valve system. The switchable half-wave plate with improved alignment control includes a layer of ferroelectric liquid crystal material sandwiched between a first transparent electrode and a second transparent electrode. The switchable half-wave plate also includes an electric field direction switching circuit configured to switch the electric field across the liquid crystal material between the forward direction and the reverse direction in response to a control signal. The switchable half-wave plate additionally includes an electric field magnitude control circuit to adjust the tilt angle in response to a signal received at a alignment control signal input. The ferroelectric liquid crystal-based light valve system according to the invention includes at least one ferroelectric liquid crystal-based spatial light modulator, an analyzer having a direction of minimum transmissivity, a ferroelectric liquid crystal-based switchable half-wave plate, and an adjustable voltage source. The voltage source is configured to adjust the magnitude of the electric field in at least one of the forward direction and reverse direction as the output voltage level is adjusted in response to a user interface or a light intensity sensor and a feedback circuit. The method of improving contrast in a ferroelectric light valve system according to the invention includes providing a ferroelectric liquid crystal-based spatial light modulator, an analyzer, a ferroelectric liquid crystal based switchable half-wave plate, and a video signal. In response to the video signal, a pixel electric field across each of the plurality of pixels is switched. Also an electric field across the switchable half-wave plate is periodically switched and the magnitude of the half-wave plate electric field is adjusted to align one of the first and the second half-wave plate director angles with one of the first and the second modulator director angles.

    摘要： Multiple motion sensor devices are included in an imaging apparatus. One or more of the motion sensor devices captures images and at least a portion of the sensor images are then processed to determine one or more motion vectors for the processed sensor images. At least one motion vector representing an amount of motion of the imager during image capture is generated when a predetermined portion of the motion vectors match.

A detector includes a hybrid filter having unpatterned and patterned filter layers and at least one light-detecting sensor that detects light in first and second wavelength bands from the patterned filter layer of the hybrid filter. The unpatterned filter layer passes light in two nonoverlapping wavelength bands relative to light in wavelength bands between or among the nonoverlapping wavelength bands. The patterned filter layer includes first and second regions configured respectively to pass light in the first and second wavelength bands of the nonoverlapping wavelength bands passed by the unpatterned filter layer.
