Absorption and fluorescence spectroscopic analysis using compact, linear variable filter based, detection platforms
… and fluorescence spectroscopic analysis using linear variable filters (LVF). The platform's potential for integration into next generation smartphones is demonstrated by the use of a conventional CMOS image sensor in conjunction with the LVF to create the detection element. An LVF-based …

Design and fabrication of a single-layer guided mode resonance grating transmission filter
To improve upon a multi-layer linear variable filter used as a spectral analyzer in a previous microfluidic lab-on-a-chip viral diagnosis assay, a single-layer spectral analyzer is envisioned. The device uses the guided-mode resonance effect, which has been used in the past to make optical stopband …
