摘要
A terahertz temporal and spatial resolution imaging system is provided. The system includes: a sample placing rack; a detection crystal, located on the exit side of the sample placing rack; a pump light generating device, for generating a pump light to irradiate the test sample; a terahertz light generating device, for generating a terahertz light to irradiate the test sample, irradiate the detection crystal after obtaining information about the test sample, and modulate an index ellipsoid of the detection crystal; a detection light generating device, for generating a detection light to irradiate the detection crystal to detect the index ellipsoid of the detection crystal, thereby indirectly obtaining the information about the test sample; and an imaging apparatus, located in an optical path after the detection light passes through the detection crystal, for collecting terahertz images of the test sample.
