Claim 0:
1. A high-speed stereo 3D multimodal imaging system, comprising:
a beam splitter, configured to generate first and second near-infrared ultrafast pulsed laser sub-beams with different angle;
a pair of plane mirrors with adjustable rotation angles, respectively configured to reflect the first and second near-infrared ultrafast pulsed laser sub-beams;
a focus lens, disposed on optical paths of the first and second near-infrared ultrafast pulsed laser sub-beams that are respectively reflected by the pair of plane mirrors and configured to tightly focus the first and the second near-infrared ultrafast pulsed laser sub-beams onto a 3D micro-nanoscale sample;
a microscope stage, configured to carry the 3D micro-nanoscale sample and three-dimensionally displace the 3D micro-nanoscale sample;
an imaging lens, disposed on optical paths of the first and second near-infrared ultrafast pulsed laser sub-beams that are tightly focused by the focus lens and configured to collect multimodal nonlinear spectral signals generated by the 3D micro-nanoscale sample due to scattering after the 3D micro-nanoscale sample is irradiated by the first and the second near-infrared ultrafast pulsed laser sub-beams that are tightly focused so as to obtain two 2D images each containing information of the 3D micro-nanoscale sample;
a large area array detector, configured to simultaneously detect the two 2D images; and
a true 3D imaging module, configured to perform a true 3D imaging according to the two detected 2D images.
