The present disclosure provides a method for correcting a light intensity measurement value is provided. The method includes: emitting detection light into a measured object; measuring a light intensity measurement value at a measurement position, and measuring light intensity of photons at a benchmark position as a light intensity reference value. A sensitivity of the light intensity of photons to a concentration change of a specific substance in the measured object is less than or equal to a preset threshold, and a change rate of the light intensity at the measurement position with a concentration of the specific substance in the measured object is greater than a change rate of the light intensity at the benchmark position with the concentration of the specific substance; correcting the light intensity measurement value by using the light intensity reference value. The present disclosure further provides a concentration measurement device.

Method for correcting light intensity measurement value and concentration measurement device in which reference value is measured at time gate fixed optical length
