Question: Fast continuous wavelet transform?

Flipping through some conference proceedings at the library some time
ago I ran across an abstract with the words "Fast Continuous Wavelet
Transform." Is there such a thing, and where do I go for more
information?

In particular, I need to calculate the wide-band ambiguity function
(time- scale plane) for a particular signal. Computational efficiency
is an issue. Can I just use the usual wavelet transform with an
orthogonal wavelet, then interpolate in the time-scale plane?
Interpolating in time seems straight- forward, but how about in the
scale direction?
