Abstract: The present invention relates to a device and method for 3D laser imaging with a longitudinal range. An optical sensor array detects a 3D image of a target through a delay difference of laser transmission between pixels. During detection, two or more identical laser pulses are sequentially emitted to the target. Each time when a pulse is emitted, a gray image of the target is formed, and multiple pulses form multiple images. By controlling a shutter, the laser pulse returned in each imaging is truncated to varying degrees, and several charge coupled device (CCD) images with different exposures are obtained. A time-varying gray curve of each pixel is extracted, and a waveform of the corresponding laser pulse is restored. A position of a pulse peak of each pixel on a time coordinate is determined to obtain the distribution of the laser delay difference between the pixels, thereby realizing 3D imaging.
