Wide-field ocean laser radar system based on Mach-Zehnder interference

The invention discloses a wide-field ocean laser radar system based on Mach-Zehnder interference, which belongs to the field of hyperspectral laser radar and comprises a laser transmitting module, a receiving and detecting module and a comprehensive control and data processing module. A core frequency discrimination component of the receiving detection module adopts a Mach-Zehnder interference component and comprises two semi-reflecting and semi-transmitting cubic prisms, two total reflection prisms and an interference arm; the number of the interference arms is two, one interference arm is inserted into a glass arm-air gap mixed structure in a short path between the two semi-reflecting and semi-transmitting cubic prisms, and the other interference arm is inserted into three sections of glass arms in a long path between the two semi-reflecting and semi-transmitting cubic prisms. The wide field of view is achieved, and meanwhile the good thermal stability is achieved. The Mach-Zehnder interference assembly out
