Spatial projection of holographic reconstructed images by blue-violet laser light is stated. Studied results are reported. Firstly, construction of mist screen is introduced, and the conditions under which optical characteristics of the screen will be improved are reported. Evaluation of improved situation is carried out by objective and subjective evaluating technics. Reconstructed images obtained by projecting blue-violet laser light are shown, and a relation between the usage of two kinds of fans and the quality of the projected images (brightness and stability) is studied. It is carried out by combining optical characteristics (objective evaluation), subjective evaluation and automatic decision making based on image analyzing process. By this, a certain relation is seen to exist between the result derived from each of the evaluating processes and the projected image judged as "good". Using this result, it is found that a clear projection of the images by blue-violet laser light is really possible.
