Abstract
An optical device is provided with an optical unit for forming an optical path of a laser beam, and a housing defining an internal space for accommodating the optical unit. The housing includes a partition for dividing the internal space into a first space and a second space. The optical unit includes a sensor arranged in the first space to detect the laser beam in the second space, a mirror arranged in the second space to define a direction of the optical path, a drive source arranged in the second space to operate the mirror to adjust the direction of the optical path, a power line for supplying power to the drive source, and a signal line for transmitting an output signal of the sensor. The signal line extends in the first space and the power line extends in the second space.
