摘要：
A novel method for simultaneous 3-D imaging using chirped ultrashort light pulses is proposed. Simultaneous imaging without scanning is possible by means of the conversion between the time and the color axes mediated by the chirped pulse. The theoretical limitation of the spatial resolution is discussed. We proved the efficacy of this method by measuring an area composing three flat steps made of three gauge blocks of different lengths with an accuracy of better than 0.3 mm. This technique is applicable for imaging of the shape of moving objects, or surface testing or inspection.
