Summary:The invention discloses a white light interference 3D sensor system control circuit, which relates to the technical field of 3D sensors and comprises a power supply module, an ARM main control module, an input and output module, a network module, a camera triggering module, a stepping motor driving module, a laser LD driving module and a grating scale encoder receiving module. According to the invention, a control system of Arm + 50nm grating ruler decoding + 2 [mu] m stepping electric appliance control + laser LD driving + high-speed camera triggering is adopted; the circuit does not need a professional motion control card, an ultrahigh-precision and high-cost motion platform, a servo/linear motor and the like, can meet the requirement of quickly triggering and acquiring images at a nanoscale position through a self-realized motion control algorithm in an ARM (Advanced RISC Machines) and only through feedback matching of a conventional stepping motor and a high-precision grating ruler, takes into account the
