Light source based on tunable laser
A tunable laser-based light source for Li-Fi communication comprises a laser (1), a first optical element (3) and a second optical element (4). The first optical element (3) is configured to reflect and/or refract the scanning light beam (2) emitted from the laser (1). The second optical element (4)...

| description | A tunable laser-based light source for Li-Fi communication comprises a laser (1), a first optical element (3) and a second optical element (4). The first optical element (3) is configured to reflect and/or refract the scanning light beam (2) emitted from the laser (1). The second optical element (4) is configured to widen the scanning light beam (2) reflected/refracted by the first optical element (3). The scanning beam (2) is configured to scan a scanning region extending in the widening direction (S1) by a first scanning length and in the scanning direction (S2) by a second scanning length. The second optical element (4) is configured to widen the scanning beam (2) in a widening direction (S1) to a width greater than the first scanning length, and the laser (1) and the first optical element (3) are configured to cooperate to enable the scanning beam (2) to sweep along the scanning direction (S2).
