| Summary: | The invention provides a duty ratio continuous adjusting method of a duty ratio continuous adjusting grating, and belongs to the field of optical and precision instruments. The duty ratio continuous adjusting grating comprises a first rectangular grating and a second rectangular grating of which the duty ratio is 50%, and the first rectangular grating and the second rectangular grating are vertically arranged and identical in direction and period. The first rectangular grating and the second rectangular 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 duty ratio continuous adjusting method, rotation of the motor in the power transmission device is controlled to drive the transmission rod to rotate and then drive the rotor to rotate, the stretching end of the rotor drives the first rectangular grating and the second rectangular grating to reversely move so as to realize duty |
