摘要： The present disclosure is directed toward measurement systems capable of optical analysis of a test sample. Embodiments in accordance with the present disclosure include a sample holder having a plurality of projections that extend from a planar surface, where the projections and planar surface collectively define an open sample-collection surface that enables an interrogation signal direct access to the test sample. The projections can be dimensioned and arranged to collectively define a geometric anti-reflection surface that is substantially non-reflective for the interrogation signal even at large angles of incidence. In some embodiments, the sample holder is configured as a reflective element that enables multiple passes of the interrogation signal through the test sample. In some embodiments, the sample holder is configured as a transmissive element. In some embodiments, the projections themselves are reflective.

摘要： Disclosed herein are systems and methods that combine: (i) the use of a first optical transformation to create patterned illumination that is directed to an imaged object such that light reflected, transmitted, scattered, or emitted by the object comprises high-resolution spatial information about the object that would not otherwise be obtained, and (ii) the use of a second optical transformation that generates an enhanced resolution optical image at a time delay and integration (TDl) image sensor that comprises all or a portion of the high-resolution information contained in said light due to the patterned illumination.

摘要： A flow cytometer can include: at least one light emitter configured to emit light in a light path; a rectangular flow cell having flow cell width that is substantially lateral to the light path and a flow cell depth that is longitudinal to the light path, wherein the light path has an interrogation width at the flow cell that is narrower than the flow cell width; and a spherical reflector positioned adjacent to the rectangular flow cell and having a concave reflective surface that has a reflective direction that is positioned substantially orthogonal with the light path such that reflected light is reflected along a reflected path that is substantially orthogonal with the light path. At least one light absorbing member is positioned at least partially around the reflected path to absorb reflected light at an angle to the reflected path.

摘要： Disclosed herein is a method including: (i) providing a light transmissive sample including nominally parallel internal facets, which are about perpendicular to an external surface of the sample; (ii) providing an optical element having a refractive index about equal to that of the sample and including an external first surface and an external second surface acutely inclined relative thereto; (iii) positioning the second surface of the optical element adjacent to the first surface of the sample; (iv) impinging light beams on the first surface of the optical element, about normally thereto; (v) sensing light beams, which exit out of the sample following passage of the impinging light beams via the optical element, transmission thereof into the sample, reflection once off the internal facets, and exit out of the sample; and (vi) based on the sensed data, computing a deviation from parallelism between the internal facets.
