  The angular power spectra of the infrared maps obtained by the DIRBE (Diffuse
InfraRed Background Experiment) instrument on the COBE satellite have been
obtained by two methods: the Hauser-Peebles method previously applied to the
DMR maps, and by Fourier transforming portions of the all-sky maps projected
onto a plane. The two methods give consistent results, and the power spectrum
of the high-latitude dust emission is C_\ell \propto \ell^{-3} in the range 2 <
\ell < 300.
