The Hubble space telescope (and any other space telescope for that matter) does not need active or adaptive optics because, in space, there are no atmospheric turbulences to distort wavefronts. Despite the absence of atmospheric fluctuations, space-qualified steering mirrors can be used on satellite platforms to correct small jitter motions caused by vibrations. Earth-bound astronomical telescopes, on the other hand, are prone to resolution degradation due to wavefront distortion caused by fluctuations in the density of the atmosphere. These fluctuations cause the twinkling of the stars. One way of compensating for these fluctuations is with fast tip/tilt steering mirrors. PI has a long history of working with telescope design teams around the world, providing cutting edge piezo-driven, high-speed tip/tilt platforms. Through a number of challenging projects, our engineers gained a great deal of experience designing large-aperture, high bandwidth tip/tilt platforms. Piezo-driven active mirrors can improve the effective resolution up to 10 times, by correcting blur caused by image jitter in real time which is particularly important during long integrations with weak light sources.
