A novel approach is used to characterize and compare the performance of night vision systems in conditions more representative of night operation in terms of spectral content. Its main advantage compared to standard testing methodologies is that it p

Silica microspheres are probed with a dual comb interferometry setup. The impulse responses of these microresonators are measured with a temporal resolution smaller than 400 fs over more than 200 ps. The amplitudes and phases of the impulse responses

This paper proposes the use of predictive analog-to-digital converters (ADC) to handle dynamic range issues in Fourier-transform spectrometers. Several predictive approaches are proposed, and one is implemented experimentally to show that the techniq

Hyperspectral data from a commercial Fourier-transform infrared imaging spectrometer is compressed using lossless Huffman coding. It is shown that, when using properly designed prediction schemes, data size can be significantly reduced even when usin

The contribution of integrating sphere speckle pattern on the instrument line shape of a Fourier-transform hyperspectral imager is investigated. A new measurement technique that minimizes the speckle effect is presented. This technique consists of ag

An extended Kalman filter, which tracks the signed speed the moving carriage, is presented. The filter uses quadrature-less reference laser fringes. Performances are evaluated on the speed estimate using experimental data highly stained by vibrations

Software field widening of a Fourier-transform spectrometer is investigated with a large multielement focal plane array detector. Experimental results are presented that stem from previous work in instrument line-shape correction. Here, pixels with c

Imaging Fourier-transform spectrometers can quickly produce massive amounts of raw data, especially when paired with large focal plane arrays. As the spatial resolution is increased, overwhelming amounts of data must be managed properly. A suitable d

An instrument line-shape correction method adapted to imaging Fourier- transform spectrometers is demonstrated. The method calibrates all pixels on the same spectral grid and permits a direct comparison of the spectral features between pixels such as
