Embodiment Construction
[0018] A quasi-optical system for high-resolution fast scanning imaging based on ellipsoidal mirror focusing, such as figure 1 and figure 2 As shown, the system includes a plane mirror 1, a condenser mirror 2 and a receiving antenna 3, the plane mirror is used to scan the field direction of the measured object 4, the condenser mirror is used to receive the reflected light of the plane mirror to converge the Gaussian beam, and the receiving antenna is used to receive The reflected light information received by the condensing mirror is transmitted to the imaging server; the condensing mirror is an ellipsoidal mirror, and a wedge mirror 5 is also arranged between the ellipsoidal mirror and the receiving antenna, and the wedge mirror receives the ellipsoidal mirror. Reflected light information, completes the scanning of the measured object in the row direction, and reflects the reflected light information to the receiving antenna, wherein the plane mirror is a pitching plane mirr...
