An inventory management system using an automated guided vehicle that moves back and forth along a guideline and that scans articles on shelves is introduced. The inventory management system may comprise: a scanning unit for recognising information about articles stacked on shelves; a guideline following a plurality of spaced apart shelves; a vehicle for supporting the scanning unit and for moving along the guideline by recognising the guideline; and a control unit for controlling the vehicle such that the vehicle can move along the guideline that is recognised using a line recognition part.

A transmission optical system comprises a concave surface mirror whose reflection surface is directed toward a deflection mirror surface and a transmission lens which is disposed between the concave surface mirror and the deflection mirror surface. A light beam deflected by a deflecting element at a first deflection angle is guided to the concave surface mirror via the transmission lens, and the light beam returned by the concave surface mirror is guided to the deflecting element via the transmission lens. In consequence, the deflecting element reflects the light beam twice, and the light beam is emitted toward a scanning lens at a second deflection angle which is larger than the first deflection angle.

The invention relates to a laser radar and its laser pulse timing adjustment method. By continuously adjusting the set threshold and / or the minimum time interval between adjacent laser pulses, there are at least A Lissajous scanning point can effectively obtain the emission timing of the laser pulse and the mapping relationship with the pixel position. When laser pulses are emitted according to this sequence, the target can be scanned stably and uniformly, which overcomes the shortcomings of Lissajous scanning such as sparse center and dense surrounding, thus making the scanning result clearer.
