A device and method for performing a preliminary test on a neat serum sample contained in a primary collection tube is provided herein. The method includes the steps of positioning of an optical probe near the primary collection tube and monitoring the neat serum sample in the primary collection tube to determine whether an interferant, such as hemolysis, icteris and lipemia are present in the serum sample. From this test, a hemolytic index, an icteric index and a lipemic index can also be established for the neat serum sample. Based upon these serum indices, the neat serum sample can be transferred to a clinical analyzer for additional testing or to waste receptacle because the sample is compromised. Additionally, a volume test can be performed on the serum sample in the primary collection tube so that the serum sample can be properly allocated during subsequent testing.

In embodiments of waveguide optics focus elements, an imaging structure includes a waveguide for viewing of an environment that is viewable with the imaging structure. The waveguide transmits light of a virtual image that is generated to appear as part of the environment for augmented-reality imaging or virtual-reality imaging. The imaging structure also includes one or more focus elements that are integrated in the waveguide and switchable to focus the virtual image at a focus depth that approximately correlates to a focal distance of the environment. The focus elements can each be implemented for a different focus depth of the virtual image, and the focus depth is adjustable based on a combination of the focus elements being switched-on or switched-off.

A system and method are disclosed for providing uniform color distribution of light emitted from a light source to an eye box in a near eye display (NED). An example of the system and method uses an optical element including two or more waveguides optimized to different colors of the visible light spectrum. The optical element further includes one or more polarization state generators for controlling the polarization of light incident on the waveguides to facilitate coupling of light into a matched waveguide, and to impede coupling of light into unmatched waveguides.

An eye-tracking system is provided. An at least partially transparent visible light waveguide has a visible light display region configured to emit visible light to an eye of a user. A light source is configured to emit at least infrared (IR) light that travels along an IR light path to the eye of the user. A microelectromechanical system (MEMS) projector positioned in the IR light path directs the IR light. At least one diffractive input coupler on an input end of the IR light path downstream of the MEMS projector diffracts at least a portion of the IR light. At least one diffractive output coupler positioned in the IR light path downstream of the diffractive input coupler receives the IR light and directs the IR light toward the eye. At least one sensor is configured to receive the IR light after being reflected by the eye.
