Laser tracking interferometric spatial coordinate measurement system and method based on dual electro-optical frequency comb

A laser tracking interferometric spatial coordinate measurement system based on a dual electro-optical frequency comb, wherein:

• the laser tracking interferometric spatial coordinate measurement system is divided into three parts comprising a precision optical tracking unit, a ranging unit based on the dual electro-optical frequency comb, and an electrical control unit;
• a part of the precision optical tracking unit is mounted on a frame body, and another part is mounted on an object under test or a space under test, wherein the ranging unit is mounted within the frame body, the electrical control unit is electrically connected to the precision optical tracking unit and the ranging unit respectively, and the electrical control unit controls the ranging unit based on the dual electro-optical frequency comb to emit a dual electro-optical frequency comb beam that is reflected and adjusted by the precision optical tracking unit to be incident on the object under test or the space under test and then received to perform spatial coordinate measurement of the object under test or the space under test.
