Abstract:
1. An optical device comprising a light-projecting unit and a light-receiving unit, wherein the light-projecting unit has a projector and a lenticular sheet arranged adjacent to each other, a first cylindrical lens array being formed on one surface of the lenticular sheet, and a second cylindrical lens array having a generatrix orthogonal to a generatrix of the first cylindrical lens array being formed on the other surface of the lenticular sheet, wherein the projector is arranged in a heat sink of the light-projecting unit, the light-receiving unit has a light-receiver, and the light-projecting unit and the light-receiving unit are arranged adjacent to each other in an integrated manner so that the light-receiver may sense light projected from the projector via the lenticular sheet and reflected from an object.
