Calculation method of reflectivity

Taro

Hi, I'm using Mid-70 for research and would like to use the reflectance information.
The manual says that "0 to 150 corresponds to the reflectivity within the range of 0 to 100% in the Lambertian reflection model", but is the angle / distance correction performed?
I would appreciate it if you could tell me the specific calculation method and formula.

For the calculation of reflectance, we consider distance correction, but not angle correction. For specific models and formulas, please refer to the paper-A Review of LIDAR Radiametrically Processing：From Ad Hoc Intensity Corrections to Ri gorous Radiometric Calibration.

Were you able to find the specific calculation method and formulas? I am also looking for that information.
