This article outlines experiments which have highlighted the rapid dev
elopment of the field of atom optics since the mid 1980s. The distingu
ishing features of the components used in atom optics are compared wit
h their conceptual analogues in light optics. The potential for atom o
ptic devices, both demonstrated and predicted, are described. Experime
nts and applications of this new technology are reviewed, and the arti
cle concludes with a synopsis of work in this field currently being un
dertaken in Australasia.
