Abstract

Each of the two telescopes of the Infrared Heterodyne Interferometer ( 11 microns) at CERGA is equiped with a near infrared ( 2 microns) imaging system using InSb photodiode and the multiplex encoding technique. Finding an astronomical source and guiding the telescope is made easier by real-time imaging of the 40 x 40 Arcsec2 field ( resolution 32 x 32). Such a system is of full interest for daytime pointing as well as pointing on purely infrared objects. In addition, a permanent correction of turbulence-induced random mispointing is performed. After a brief reminding of the principle, the system is described and the actual as well as the potential capabilities are given.
