In order to produce a holographic reconstructed image in colors, we must study sufficiently the characteristics of the images reproduced not only by red or green color laser lights but also, in particular, by blue color laser light. But in general,if we use, in reproduction of the images, the laser lights with short wave length, the reconstruction comes to be more difficult. For this reason, it seems to be very few to find the results concerning the reconstruction with the use of blue color laser light.It appears to lead us to an unfortunate problem of the restriction on the color region of the recovered holographic images. Our task is to study carefully the characteristics of the recovered images performed by the blue color laser lights of short wave length, and to make much efforts to enlarge the presentable color region of the reproduced images. In this report,we have studied possibility of the reconstruction of holographic images by the use of blue-violet laser lights. As this result,we have found some condition that makes us possible to perform a reproduction of holographic images by the use of blue-violet laser lights. This seems to suggest some possibility of an extension of the color region for the recovered holographic images.
