  In this paper we present an evolution of the single-pixel camera
architecture, called 'pushframe', which addresses the limitations of pushbroom
cameras in space-based applications. In particular, it is well-suited to
observing fast moving scenes while retaining high spatial resolution and
sensitivity. We show that the system is capable of producing colour images with
good fidelity and scalable resolution performance. The principle of our design
places no restriction on the spectral range to be captured, making it suitable
for wide infrared imaging.
