It is also used to inspect and measure the inner walls of biological cavities, and its results have been highly acclaimed.

の域に達していない現状にあった。Problems to be Solved by the Invention Incidentally, this type of imaging device cannot be achieved by simply incorporating a hologram imaging device into the endoscope itself, and is particularly suitable for use with endoscopes used for inspection and diagnosis of the inner wall of biological cavities. Incorporating a hologram creation device that covers a wide field of view in the limited space of the endoscope would unnecessarily increase the diameter of the so-called insertion section of the endoscope, making it virtually impossible. Also, for industrial use, incorporating a hologram creation device that covers such a wide range of subjects is an economical problem, as the endoscope must be large in diameter and expensive. There were 9 drawbacks, and the current situation was that it had not reached the level of practical use.
