Review of pedestrian detection techniques in automotive far-infrared video
, 2015The use of advanced driver assistance systems is becoming increasingly common in road-going vehicles. One application of these driver assistance systems is in the automated detection of vulnerable road users, such as pedestrians, using automotive far ...

Prospects for far infrared arrays
Experimental Astronomy, 1994We report initial performance measurements of a 1/8 scale version of a 32x32 pixel array under development for SIRTF. This array demonstrates that we can reach the sensitivity limits set by the natural backgrounds in space while providing good imaging and photometric performance.

The Far Infrared Spectrum of the NO Dimer
Journal of Molecular Spectroscopy, 1999The far-infrared spectrum of the NO dimer in the gas phase has been observed for the first time using a long-path (180 m) cooled (99 K) absorption cell and a Bomem Fourier transform spectrometer. Four weak vibration-rotation bands were detected in the 120-450 cm-1 region and assigned to intermolecular vibrations of the cis-planar ON-NO complex.

1974
One of the exciting Challenges in recent years was to develop a coherent radiation source which would bridge the energy region between the infrared and the microwaves. We have achieved this objective with the use of two high power CO2 TEA lasers and a non-collinear phase matching technique in a crystal of GaAs.1 Our results represent one of several ...

Detection Limits in the Far Infrared
Space Science Reviews, 1995The advent of far infrared arrays will change fundamentally the means of analyzing observations in this spectral region. Sources much fainter than traditional “confusion limits” will be extracted from images by using computer algorithms similar to CLEAN or DAOPHOT.

Investigations in the Far Infrared
Physical Review, 1931An instrument is described for investigations of the reflectivity, transmissivity and emission of various materials over the spectral range 20 to 150\ensuremath{\mu}. The following measurements are reported: Reflectivities of rough surfaces, galena, $\ensuremath{\beta}$-magnesia, zincite, stibinite, corundum, sphalerite, molybdenite and cuprite ...

Far-Infrared Instrumentation [PDF]
, 1971 The commercially available far-infrared instrumentation will be discussed and summarized. The prism instruments will only be briefly mentioned, since the emphasis has now passed to the grating instruments. As a result, the Beckman IR-11 and the Perkin-Elmer No. 301 will be comprehensively discussed.

Far Infrared Interference Filters
Applied Optics, 1969Capacitive meshes for far ir, low pass filters are prepared from Cu layers on 2.5 micro plastic film. The properties of these meshes of different mesh constants g with their different combinations in two-mesh, fourmesh, and eight-mesh filters are studied in the spectral region 160 cm(-1) to 10 cm(-1) by the use of a grating spectrometer.

Interference Filters for the Far Infrared
Applied Optics, 1968Perforated metal plates (grids) of various kinds are used for the construction of transmission filters for the far ir. Examples are given of filters with low pass, high pass, bandpass, and bandstop characteristics with steep slopes. These filters are the optical equivalents of microwave waveguide filters.
