The research examines the role of external factors—ambient illumination, surface reflectivity, and laser

incidence angle—on the accuracy as well as stability of distance measurements with the compact LiDAR

sensor TF-Luna. A MATLAB model for simulation was created to assess how each of these parameters

influence the accuracy of the output of the sensor. The model includes Lambert’s cosine law, variable

reflectivity values between 0.1 and 0.9, and up to 70,000 lux illumination levels. The simulation outputs

show that high values of brightness, low reflective surfaces, and high angles of incidence dramatically

reduce the accuracy of measurement, raising error bounds as well as the likelihood of failure. The evidence

supports critical reliance of TF-Luna’s operation on environmental factors. Recommendations have been

proposed for alleviating such effects when the sensor is employed for mobile robotics and remote sensing

purposes.
