Document Type and Number:
WIPO Patent Application WO/2022/186113
Kind Code:
A1
Abstract:
The purpose of the present invention is provide an optical transmission device with which it is possible to adjust the orientations of a light-projecting optical system and a light-receiving optical system by using a simple structure. This optical transmission device performs optical communication between a light-projecting unit, which includes an emission means for emitting communication light and the light-projecting optical system, and a light-receiving unit, which includes the light-receiving optical system and a light-receiving means for receiving the communication light, the optical transmission device being characterized by having a first holding member that holds the light-receiving optical system, and a second holding member that holds the light-receiving means and that is detachably secured to the first holding member.
