Patent ID: 10060850

Abstract:
An example assembly includes a target holder that retains a target in a detection region. A reflective surface reflects at least part of a focused spot of light to provide resultant light. An irradiation system irradiates at least part of the detection region with the focused spot of light. A motion system causes motion of the focused spot of light relative to the reflective surface. A detection system detects the resultant light. An example device, e.g., a lab-on-chip, includes a substrate, a sample inlet, and a reflective grating. The grating is retains a fluidic sample in a detection region fluidically connected to the sample inlet. The detection region is operatively arranged with respect to the reflective grating so that at least a portion of light passing through the detection region towards the reflective grating also passes through the detection region after reflecting off the reflective grating.
