C HAPTER 5 Heavy launch vehicle. The minimum array size of 120 × 20 m is constrained by the desire to maintain at least 20 m separation between the centers of the spacecraft. The maximum array size of 612 × 102 m is limited by the maximum distance (311 m) over which the beams can be relayed without introducing significant amounts of stray light for the thermal shields. These constraints result in a dynamic range of 5:1 in the array size. Figure 5-2. The main optical components of the collector telescope spacecraft. 100
<strong>TPF</strong>-I F L I G H T B ASELINE D ESIGN 5.3 Optical Beam Train 5.3.1 Collector Spacecraft The beam train consists of the following main elements. First the collector telescopes, a three-mirror design. Beneath the telescope primary mirror, see Figure 5-2, are systems for maintaining pointing at the star and internal alignment and metrology systems. A deformable mirror (DM) is included in the beamtrain to allow wavefront correction; further analysis will be needed to examine the necessity for this unit and its range of operation. Following recollimation of the beam, a number of fold mirrors transmit the beam up to near the top of the telescope body and send it to the next spacecraft. The next spacecraft then relays the beam to the beamcombiner spacecraft.
