Abstract
Spectrometry is a vital tool in science, medicine, and technology. As with other instruments, efforts are constantly being made to make spectrometers smaller, cheaper, and more compact. With recent developments in low-cost and high-resolution cameras, the possibility now exists for portable spectrometers to now be integrated into small form-factors. In particular, filter-array based spectrometers are promising, as they allow for the filter to be fabricated directly on the sensor surface, for a compact and robust package with no moving parts. Here, we demonstrate a novel method for spectrometry that uses an array of optical cavities to spatially encode the light of interest, and then recovers it using a reconstruction algorithm. It has the unique capability for a combination of high resolution, larger working bandwidth, and high sensitivity, which makes it a promising candidate whenever a small, robust, and flexible spectrometer is needed.
