    摘要： In a laser picture formation device which forms a vide image by irradiating lights emitted from plural laser light sources (1a, 1b, 1c) which obtains monochromatic lights from laser lights which are outputted from the respective laser light emission parts to spatial light modulators (5a, 5b, 5c), each of the plural laser light sources (1a, 1b, 1c) detect the output of laser light which is emitted from the respective laser light emission parts on the basis of the modulation input signal which for modulating the spatial light modulator. Thereby, it is possible to confirm the deterioration situation of the respective laser light emission parts without deteriorating the video images which are projected onto the screen, as well as without separating the synthesized light respectively.
