    摘要： Systems and methods for positioning a multi-featured biological array relative to a signal acquisition device. Detection of the array's positional deviation may be achieved by a calibration beam reflected from the array surface and detected by a position sensitive detector (PSD). The PSD-measured positional deviation can be transformed and used in a control loop to correct for positional variations of the array. The calibration beam and PSD may also be used to detect the array or feature boundaries, thereby allowing lateral centering or positioning of the array relative to the signal acquisition device.

    摘要： An apparatus and method are provided for differentiating multiple detectable signals by excitation wavelength. The apparatus can include a light source that can emit respective excitation light wavelengths or wavelength ranges towards a sample in a sample retaining region, for example, in a well. The sample can contain two or more detectable markers, for example, fluorescent dyes, each of which can be capable of generating increased detectable emissions when excited in the presence of a target component. The detectable markers can have excitation wavelength ranges and/or emission wavelength ranges that overlap with the ranges of the other detectable markers. A detector can be arranged for detecting an emission wavelength or wavelength range emitted from a first marker within the overlapping wavelength range of at least one of the other markers.
