Abstract
A compact spectrometer is disclosed that is suitable for use in mobile devices such as cellular telephones. In preferred embodiments, the spectrometer comprises a filter, at least one Fourier transform focusing element, a micro-lens array, and a detector, but does not use any dispersive elements. Methods for using the spectrometer as an end-user device for performing on-site determinations of food quality, in particular, by comparison with an updatable database accessible by all users of the device, are also disclosed.

(canceled)
A compact spectrometer system for obtaining a spectrum of a sample, the compact spectrometer system comprising:
- an optical detector configured to detect light emanating from the sample, wherein the optical detector is configured to measure spectral intensity and is configured to detect light of four or more wavelengths, and generate raw spectral data in response to measured spectral intensity;
- a plurality of optical filters located between the sample and the optical detector;
- a local processing unit configured to convert raw spectral data into processed spectral intensity data;
- a communication module configured to be in communication with the local processing unit and a remote processor, wherein the communication module is configured to transmit the processed spectral intensity data from the local processing unit to the remote processing unit, and
- wherein the remote processing unit is configured to generate the spectrum of the sample in response to the raw spectral data.
