Study of a design for a large infrared telescope, consisting of six independent optical systems shows that it is possible to control the optical path differences and phases such that aperture synthesis can be achieved. A thin compensating prism in each optical path can compensate simultaneously the path errors for all objects in the field of view of the telescope. Design parameters for a 5.6-m system are given.
