Abstract

The invention discloses a close distance three-dimensional holographic imaging device and method. The device comprises a main body frame. The top and bottom of the main body frame are provided with a first circular rail and a second circular rail. The first circular rail and the second circular rail are equipped with a first holographic probe and a second holographic probe. The centers of the first circular rail and the second circular rail are provided with a first image signal transmitting and receiving device and a second image signal transmitting and receiving device. A scanning area is formed at the center of the main body frame. An object to be imaged is placed in the scanning area. The device and the method have the advantages of novel structural design, the fast scanning and 3D imaging of an object, and a clear image.

Description

technical field [0001] The invention relates to the technical field of display racks, in particular to a short-distance three-dimensional holographic imaging device. Background technique [0002] The integration of frequency-modulated continuous wave signal and different wavelength signal imaging technology promotes the formation of a broadband, effective, low-consumption, high-quality imaging system, especially in the application of security detection systems, when the antenna array continuously transmits and receives frequency-modulated continuous wave signal, its uninterrupted motion effect will no longer be ignored. Therefore, the traditional discontinuous method in the synthetic aperture imaging algorithm needs to be optimized and improved in the frequency-modulated continuous wave imaging processing. Traditional algorithms, such as wave number domain algorithms, frequency The scaling algorithm and the range Doppler algorithm, etc., are all focused on the optimization o...
