<P>PROBLEM TO BE SOLVED: To provide a video transmission system capable of carrying out optical axis alignment without the use of a reflecting plate and easily controlling on / off of a visible optical laser emission section. <P>SOLUTION: In the video transmission system provided with a transmitter side module for converting a video signal into an invisible optical laser and providing an output of the laser and a receiver side module for receiving the invisible optical laser outputted from the transmitter side module and converting it into a video signal, the receiver side module is provided with a visible optical laser output means for emitting a visible optical laser on the same optical axis as that of a light receiving section of the invisible optical laser, and a mark to specify a region onto which the visible optical laser is made incident at optical alignment is marked to the surrounding of an emission port of the invisible optical laser in the transmitter side module, and the transmitter side module is provided with an exclusive use remote controller for wirelessly remotely controlling on / off of the visible optical laser output means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
