Magdalena Ridge Observatory – MROi

The Magdalena Ridge Observatory Interferometer (MROI) is a high-sensitivity imaging optical/IR interferometer in construction on the Magdalena Ridge mountain of Socorro in New Mexico. Up to ten “unit telescopes” will be moveable on an equilateral “Y” shape array providing snapshot imaging capabilities with a sub-milliarcsecond resolution. The telescopes can be relocated on 28 stations distant of 7.5m to 350m.

The high sensitivity is obtained thanks to the innovative configuration for the 1.4m unit telescopes. The telescope consists in a Mersenne beam compressor supported onto an elevation over elevation mount. The 95 mm diameter output collimated beam is sent througt the outer elevation mount by a tertiary mirror articulated around the inner elevation axis. The star light hits only three surfaces in the telescope. The throughput is therefore significantly higher compared to a coudé train configuration.


As the main contractor for the development of the unit telescope, AMOS is taking advantage of its experience in the design of telescopes dedicated to interferometry to design the complete telescope in a short time frame.
