摘要： The controller 170 controls the output power of the semiconductor laser device 100a depending on the temperature of the semiconductor laser device 100a acquired by the temperature sensor 130. The controller 170 references the correspondence table 510 when the sensor temperature Ts is obtained, obtains the output power PWs corresponding to the sensor temperature Ts, and controls the power supply driving circuit 150a so that the output power per unit time of the semiconductor laser device 100a will be the output power PWs. Thus increase in temperature of the semiconductor laser device is able to be prevented through reducing the output power by controlling the amount of power supplied to the semiconductor laser device. As a result, it is possible to prevent reductions in the service life of the semiconductor laser device, even when there is a failure in a cooling device that cools the semiconductor laser device, and even when the device is used in a high temperature environment not envisioned at the time of manufacturing.

The group of prisms includes prism elements each of which has at least a refracting surface. Light from one of the opening sections is incident on at least one portion of the group of prisms. A direction of the refracting surface and a tilt angle are arranged so that an opening section image is guided onto a black matrix image on a screen a distance from the group of prisms.
