In biotechnology and medical diagnostics there is a large demand for the analysis of enormous sets of samples. Optical detection systems such as micro-array scanners, flow cytometers, and fluorescence microscopes are the standard work horse instrumentation for these applications. While these systems have proven successful, they are frequently based on the frame of a standard optical microscope which has tradeoffs in field of view, resolution, and light collection. By designing optical systems using a priori knowledge of the sample, many of these tradeoffs can be circumvented. In the MOIRE lab, we will investigate optical detection systems based on microfabricated components, such as lens arrays, computer generated holograms, and artificial dielectrics. By integrating these components with microfluidics and high speed cameras, we hope to realize a new generation of optical diagnostic devices.
