Abstract: 本发明公开了一种基于全光傅里叶变换及双光学频率梳时域干涉的超高分辨率光谱测量方法及系统，方法为两个光学频率梳光源产生两路具有微小重复频率差的超短脉冲序列；一路超短脉冲通过色散作用得到扫频泵浦脉冲序列，并基于四波混频原理构成时域透镜；利用时域透镜的傅里叶变换功能对待测光信号进行波长到时间的转换；所得携带了待测光谱信息的光信号通过波长统一后与另一路超短脉冲进行干涉叠加；所得干涉信号转换为电信号并经过后续处理即可得到待测光信号的光谱。本发明能实现超高的光谱分辨率，适用于测量任意形式的光信号，且有效地降低了系统成本。

Abstract: Techniques for hyperspectral imaging, including a device for hyperspectral imaging including at least one tunable interferometer including a thin layer of material disposed between two or more broadband mirrors. Electrodes placed on either side of the tunable interferometer can be coupled to a voltage control circuit, and upon application of a voltage across the tunable interferometer, the distance between the mirrors can be modulated by physically altering the dimensions of the thin layer of material, which can uniformly load the broadband mirrors. Physically altering the dimensions of the thin layer of material can include one or more of deformation of a soft material, piezostrictrive actuation of a piezostrictrive material, or electrostrictive actuation of an electrostrictive material.

Abstract: Snapshot imaging Fourier transform spectrometers include a lens array that produces sub-images that are directed through a birefringent interferometer in orthogonal polarization eigenstates that acquire an optical path difference. Interference patterns based on this OPD can be Fourier transformed to obtain a spectral image. In some examples, polarizing gratings provide a spatial heterodyne frequency and offset the spectra.
