METHOD AND APPARATUS FOR MULTIPLEXED FABRY-PEROT SPECTROSCOPY |
| 摘要 |
A method of optical spectroscopy and a device for use in optical spectroscopy. The device includes a substrate, and a plurality of etalon cavities affixed to or coupled to the substrate. A signal is received from a Fabry-Perot interferometer. The signal is sampled using the device according to a generalized Nyquist-Shannon sampling criterion. The signal is sampled using the device according to a phase differential criterion for wave number resolution. An input spectrum for the signal is reconstructed based on the signal sampled according to the generalized Nyquist-Shannon sampling criterion and the signal sampled according to the phase differential criterion for wave number resolution. |

1. A method comprising:
receiving a signal from a Fabry-Perot interferometer; sampling the signal according to a generalized Nyquist-Shannon sampling criterion; sampling the signal according to a phase differential criterion for wave number resolution; and reconstructing an input spectrum for the signal based on the signal sampled according to the generalized Nyquist-Shannon sampling criterion and the signal sampled according to the phase differential criterion for wave number resolution. |
