Abstract: There is described a mission control system having an operator seat; a head-mounted display and digital gloves worn by the operator; a headset having a microphone and integrated in the head-mounted display; a tracker for tracking the movements of the head-mounted display and the digital gloves; and a mission computer housed in the operator seat and connected to the head-mounted display, to the digital gloves, to the headset, to the microphone, and to the tracker, to allow the operator to impart gestural commands by means of the digital gloves, and voice commands by means of the microphone, and to receive visual information by means of the head-mounted display, and audio information by means of the headset.

Abstract: The spectrometer comprises at least a first optical path for a beam of electromagnetic radiation, along which the following are set: a beam-entry slit (1) for an incoming beam; a collimator (5) comprising a convergent spherical mirror for collimation of the incoming beam; a first dispersor (9) for dispersion of the beam into its chromatic components; a first focusing system (19); and a first detector (21) which receives the beam dispersed and focused by said first focusing system. Set along the first optical path there is set at least one first aspherical corrector element (7; 17) comprising an aspherical mirror for correction of spherical aberration.

Abstract: The spectrometer comprises, in combination: a slit (1) for the entry of a light beam; a collimator; a dispersion system (9); focusing means and a detector (13). The collimator comprises at least a first concave spherical mirror (3) and at least a first Schmidt plate (5) in an off-axis arrangement.
