The invention provides a sensitivity correction method of an optically stimulated luminescence dating experiment. The sensitivity correction method comprises the following steps of, in each loop teststep, calculating a regenerative-dose luminescence signal value and a test-dose luminescence signal value which are obtained through measurement, and acquiring a current regenerative-dose sensitivitychange value, wherein the current regenerative-dose sensitivity change value is a change quantity of the luminescence signal value measured by an equivalent regenerative dose; correcting the current regenerative-dose sensitivity change value, and obtaining a corrected regenerative-dose sensitivity change value, wherein a current test-dose sensitivity change value is a difference value between thetest-dose luminescence signal value measured in a previous loop test step and a current test-dose luminescence signal value measured in a current loop test step; and correcting the current test-dose sensitivity change value, and obtaining a corrected test-dose sensitivity change value. The sensitivity correction method can be used for effectively optimizing a correction method of a sensitivity change, so as to improve the test accuracy and reliability of an equivalent dose of a sample.
