Abstract

The Large Millimeter Telescope Alfonso Serrano (LMT) is a 50m-diameter radio telescope for millimeter-wave astronomy. The performance of large radio telescopes like the LMT is often limited by their response to deformations caused by thermal gradients within the antenna structure. In this paper, we describe a development project to build a real time metrology system for the LMT. The Large Aperture Surface Error Recovery System (LASERS) will measure, on time scales of a minute in real time, the shape of the antenna's primary mirror and the location of its secondary mirror to high accuracy. The LMT's existing active systems may then be used to maintain precise alignment of the telescope’s primary surface and its secondary.
