Paper Abstract

Two high-precision and movable telescopes of 65 inch aperture are being constructed for long baseline infrared spatial interferometry (1). The telescopes are of novel design and emphasize the control of optical pathlengths and of telescope positions to a precision of about one micron. This will allow the relative phase of interference fringes to be determined over rather large angles of the sky and over some period of time, so that high precision astrometry as well as aperture synthesis can be done at wavelengths near 10 microns.
