Scientific paper

In the present 'one-dimensional' (i.e., 10 x 800 cm) telescope aperture for high angular speckle interferometry, image plane speckles are elongated in a direction perpendicular to the entrance pupil. For a given amount of atmospheric turbulence, the one-dimensional pupil gives a contrast gain in the high frequency region. In association with a spectroscope, a one-dimensional telescope allows the representation of the spatial-spectral plane without photon loss because of its good match with the spectroscope slit. Attention is given to the design of a domeless, altazimuthal mount low cost prototype for solar observations.
