The invention, which belongs to the photoelectric
imaging technology field, relates to a multispectral stripe tube three-dimensional
lidar imaging apparatus. The apparatus comprises: a multi-
wavelength laser, a beam expanding
prism, a reception
telescope, a
diffraction grating spectroscope, a convex lens, optical filters, a stripe tube, a
coupling light cone, and a
CCD camera. A mixing multi-
wavelength laser beam that is emitted by the multi-
wavelength laser passes through the beam expanding
prism and then is shot at an object and is reflected; the reflected laser beam is received by the reception
telescope and is gathered to the
diffraction grating spectroscope; and then the gathered laser beam passes through the convex lens and is focused on the optical filters; the focused laser beam bombards a photoelectric
cathode of the stripe tube to generate a plurality of
electron beams though a slit and the plurality of
electron beams bombard a fluorescent screen in the stripe tube; and then a multispectral strip image is coupled through the
coupling light cone and is imaged on the
CCD camera. According to the invention, a multi-spectral detection technology is integrated into a stripe tube
lidar imaging apparatus, so that accuracy of object imaging and richness of information are improved; and a specific wavelength can detect a
weak signal; therefore, an application arrange of the stripe tube
lidar imaging detection apparatus is expanded.
