An image deconvolution algorithm is applied to 1 arcsec resolution images of the 3C 273 jet, yielding 0.5 arcsec resolution restored images with a quadratic reconstruction error of 12 percent. The optical jet appears to be made of 7 knots along the ridge line having a regular spacing of 1.2 arcsec. The reality of these knots is discussed. Within reconstruction errors, the optical and radio structures appear quite similar. The spectrum of the jet steepens outwards.
