Abstract: This far-infrared spectroscopy device is provided with: a variable wavelength far-infrared light source that generates first far-infrared light; an illuminating optical system that irradiates a sample with the first far-infrared light; a detecting nonlinear optical crystal that converts second far-infrared light into near-infrared light using pump light, said second far-infrared light having been transmitted from the sample; and a far-infrared image-forming optical system that forms an image of the sample in the detecting nonlinear optical crystal. The irradiation position of the first far-infrared light on the sample does not depend on the wavelength of the first far-infrared light.

The image sensor (28) acquires data to construct a two-dimensional spectral image (13A) during a data acquisition time (346). The illumination source (14) generates an illumination beam (16) that illuminates the sample (10) to create a modified beam (16I) that follow a beam path (16B) from the sample (10) to the image sensor (28). The refractive, optical element (24A) is spaced apart a separation distance (42) from the sample (10) along the beam path (16B). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), controls the mover assembly (29) (24C) to modulate the separation distance (42), and controls the image sensor (28) to capture the data.

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.
