    Abstract: The presently described techniques relate generally to providing motion feedback (e.g., motion system calibration and/or sample alignment) in the context of an imaging system (such as a time delay and integration (TDI) based imaging system). The architecture and techniques discussed may achieve nanoscale control and calibration of a movement feedback system without a high-resolution encoder subsystem or, in the alternative embodiments, with a lower resolution (and correspondingly less expensive) encoder subsystem than might otherwise be employed. By way of example, certain embodiments described herein relate to ascertaining or calibrating linear motion of a sample holder surface using nanoscale features (e.g., sample sites or nanowells or lithographically patterned features) provided on a surface of the sample holder.

    Abstract: A method comprises: directing, using an objective and a first reflective surface, first autofocus light toward a sensor, the first autofocus light reflected from a first surface of a substrate; preventing second autofocus light from reaching the sensor, the second autofocus light reflected from a second surface of the substrate; and directing, using the objective and a second reflective surface, emission light toward the sensor, the emission light originating from a sample at the substrate.

    Abstract: Systems and methods disclosed herein include an imaging system that may include a laser diode source; an objective lens positioned to direct a focus tracking beam from the light source onto a location in a sample container and to receive the focus tracking beam reflected from the sample; and an image sensor that may include a plurality of pixel locations to receive focus tracking beam that is reflected off of the location in the sample container, where the reflected focus tracking beam may create a spot on the image sensor. Some examples may further include a laser diode light source that may be operated at a power level that is above a power level for operation at an Amplified Spontaneous Emission (“ASE”) mode, but below a power level for single mode operation.

    Abstract: The disclosure provides for structured illumination microscopy (SIM) imaging systems. In one set of implementations, a SIM imaging system may be implemented as a multi-arm SIM imaging system, whereby each arm of the system includes a light emitter and a beam splitter (e.g., a transmissive diffraction grating) having a specific, fixed orientation with respect to the system's optical axis. In a second set of implementations, a SIM imaging system may be implemented as a multiple beam splitter slide SIM imaging system, where one linear motion stage is mounted with multiple beam splitters having a corresponding, fixed orientation with respect to the system's optical axis. In a third set of implementations, a SIM imaging system may be implemented as a pattern angle spatial selection SIM imaging system, whereby a fixed two-dimensional diffraction grating is used in combination with a spatial filter wheel to project one-dimensional fringe patterns on a sample.

    Abstract: Apparatus and methods for controlling heating of an objective in a linescanning sequencing system to improve resolution are disclosed. In accordance with a first implementation, an apparatus includes or comprises a beam source for providing input radiation and a beam shaping group including or comprising one or more optical elements positioned to receive the input radiation from the beam source, and to perform beam shaping on the input radiation to form a shaped beam. The apparatus further including or comprising an objective positioned to receive the shaped beam and to transform the shaped beam into a probe beam and configured to provide the probe beam to a focal plane of the objective for optically probing a sample. The beam shaping group is configured to adjust one or more properties of the shaped beam over time to generally uniformly heat the objective over a region of incidence for the shaped beam.

    Abstract: Apparatus and methods for transmitting light are disclosed. In an implementation, an apparatus includes a collimator at an input end positioned to receive an input beam from a fiber beam source and to produce a collimated beam. The apparatus further includes a beam shaping group having one or more optical elements and positioned to receive the collimated beam from the collimator and format the collimated beam into a shaped propagation beam having a substantially rectangular cross-section in a far field. The apparatus further includes an objective stage for optically probing a sample, such as a flow cell, using substantially rectangular cross-section sampling beam, where fluorescence from the sample is captured by a line sensor for detecting properties of the sample, such as chemical reactions therein.
