1967 Physics Lett. A. 25 89 (title) A posteriori image-correcting deconvolution by holographic Fourier-transform division.

1970 Jrnl. Res. Nat. Bureau of Standards (U.S.) 74 A. 436/2 After change of variable, F(ζ) is inverted by a sequential deconvolution procedure.

1975 Sci. Amer. July 48/2 Digital techniques can be used for ‘blind deconvolution’, defined as the problem of unscrambling two signals that have become ‘convolved’ when both are unknown.

1980 Nature 29 May 313/1 At our resolution, deconvolution of this band and the 342 nm HONO band present in the reference spectrum is difficult, leading to distortion and masking of the HONO band.
