Optical wireless transmission system for performing optical space transmission, and optical transmitter used therein
Abstract:
An optical transmitter for performing high-rate data communication by means of optical space transmission is provided, which can reliably perform optical axis adjustment manually and visually, and can prevent a device from being made large in size and manufacturing cost of the device from being increased by using an simply-constructed optical transmitter. Thus, the optical transmitter of the present invention comprises an incident beam restriction section operable to allow only a visible beam which is emitted by a terminal located within a range in which an infrared beam is emitted and incident thereon to pass therethrough, a reflection section operable to reflect the visible beam which has passed through the incident beam restriction section, and a light source operable to emit the infrared beam to pass through the reflection section according to a data transmission request signal from the terminal.
