A discussion on infared astronomy - Near infrared night sky background
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1969We have carried out near infrared observations on wide fields of the sky, using both a rocket-borne telescope and ground-based equipment. The rocket observations covered the spectral range of 1 to 8 μm. The ground-based observations were carried out in a narrow spectral region around 1.085 μm.

A discussion on infared astronomy - Near infrared photometry of late-type stars
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1969A multi-band photoelectric photometer for observations in the ultraviolet, blue and visible and the infrared bands W (1.06μm), X (1.13 μm, Y (1.63 μm) and Z (2.21 μm) has been constructed and applied to both stellar and planetary observations ...

Using the results of photometry applied to speckle image reconstructions of the triple stellar system LHS1070 in the near infrared, we compare quantitatively the performance of shift-and-add and bispectrum image reconstruction methods and find that comparable results can be obtained.

LINC-NIRVANA (LN) is the near-infrared, Fizeau-type imaging interferometer for the large binocular telescope (LBT) on Mt. Graham, Arizona (elevation of 3267 m). The instrument is currently being built by a consortium of German and Italian institutes under the leadership of the Max Planck Institute for Astronomy in Heidelberg, Germany.

It is well known that atmospheric turbulence limits the resolution available to ground based astronomical observations to 0.5-1.0 arcseconds in the infrared. The advent of speckle interferometry in the 1970’s [1] has allowed the recovery of diffraction limited Fourier modulus information of astronomical objects of interest to be attempted routinely.
