Two retro-mirrors, each consisting of a plane mirror and a parabolic mirror, are used; one retro-mirror is held fixed while the other is scanned to obtain the interferogram (the Fourier transform of the spectrum). Available in a number of configurations, using retro-reflectors or plane mirrors, the system can be applied to axis lengths of up to 4 meters. In Lift (insufficient), which shows an airplane apparently having trouble clearing a light tower, the shape of the plane mirrors the triangle of the tower. |
