Summary:The invention provides a contrast continuous adjusting method of a contrast continuous adjusting grating, and belongs to the field of optical and precision instruments. The contrast continuous adjusting grating comprises a first sinusoidal grating and a second sinusoidal grating which are vertically arranged and identical in direction and period. The first sinusoidal grating and the second sinusoidal grating reversely move under adjustment of a grating adjusting mechanism. The grating adjusting mechanism is powered by a power transmission device installed on a base. According to the contrast continuous adjusting method, the transmission rod is driven to rotate by controlling rotation of the motor in the power transmission device and then the rotor is driven to rotate and the stretching endof the rotor drives the first sinusoidal grating and the second sinusoidal grating to reversely move so as to realize contrast continuous adjustment. Rotation of the motor can be controlled anytime according to the actual re
