摘要： A system and method for imaging biological samples on multiple surfaces of a support structure are disclosed. The support structure may be a flow cell through which a reagent fluid is allowed to flow and interact with the biological samples. Excitation radiation from at least one radiation source may be used to excite the biological samples on multiple surfaces. In this manner, fluorescent emission radiation may be generated from the biological samples and subsequently captured and detected by detection optics and at least one detector. The detected fluorescent emission radiation may then be used to generate image data. This imaging of multiple surfaces may be accomplished either sequentially or simultaneously. In addition, the techniques of the present invention may be used with any type of imaging system. For instance, both epifluorescent and total internal reflection methods may benefit from the techniques of the present invention.

A rectangular detector array having a horizontal dimension that is longer than the vertical dimension can be used along with imaging optics positioned to direct a rectangular image of a portion of a sample to the rectangular detector array. A scanning device can be configured to scan the sample in a scan-axis dimension, wherein the vertical dimension for the rectangular detector array and the shorter of the two rectangular dimensions for the image are in the scan-axis dimension, and wherein the vertical dimension for the rectangular detector array is short enough to achieve confocality in a single axis.

摘要： A logic module for an FPGA includes a LUT formed from an N-level tree of 2:1 multiplexers. Each of the N inputs to the LUT is connected to the select inputs of the multiplexers in one level of the tree. Each of the data inputs at the leaves of the tree is driven by a configuration memory cell that produces either a logic 0 or a logic 1. The output of the single multiplexer at the last level of the tree forms a Y output and is coupled to one input of an XOR gate and to the select input of a two-input carry multiplexer. The 0 input of the carry multiplexer is coupled to a G input. A CI input is coupled to the other input of the XOR gate and to the 1 input of the carry multiplexer.

摘要： Systems and methods for facilitating focusing of an image scanner, such as a confocal microscope, are disclosed. Measurement of optical characteristics in certain areas of a test sample are compared to stored or baseline optical characteristic profiles to determine an appropriate correction to properly focus the scanner. In one aspect, the method includes obtaining a dynamic profile at a current detection region of a test sample and associating the dynamic profile to a profile selected from a set of stored baseline profiles. Each of the stored baseline profiles is associated with a correction.
