[Problems to be Solved] In the conventional transmitting/receiving device as described above, there is a problem of where to install the optical system.1 For example, the size and shape become large due to mechanical positional relationships, or conversely, the size and shape are large due to the mechanical positional relationship. Both systems have completely different frequency bands, such as the fact that the functionality of both systems is significantly reduced due to the restriction that they must be housed within the same system, and the light wave detector cannot be effectively shielded from the transmission power of radar etc. There was a problem in that there were many negative effects of having both.
