The mirrors are rigidly coupled to a principal pointing mirror (2) to follow the mirror (2) during a change in observation direction (D 0). The origination directions of the rays directed by the mirrors (4, 5) are separated by an angle greater than 10[deg]. An independent claim is also included for a method for implementing an optical system.",
