In the present paper, it is discussed how to treat with the analytical and numerical solutions of searchlight problem with faint background light on flat terrain bounded below by a diffuse reflector. It is elucidated that the angular distribution of radiation emergent from the top of the turbid slab of finite thickness with a point source on top is discussed by imbedding the problem within a family of parameters, allowing for the numerical solution via Monte Carlo method.
