A laser microscope or a color laser microscope in which a high-resolution image of a sample can be taken without using an acoustic optical element. A rectilinear light beam generating device is used for converting a laser beam into an incoherent rectilinear light beam diverging in a certain direction. Specifically, a laser beam emitted from laser source(s) is converted into an incoherent rectilinear light beam diverging in a certain direction by the rectilinear light beam generating device, and the rectilinear light beam is projected on a sample via a beam deflecting device so as to scan a surface of the sample. The beam reflected from the sample is received by a linear image sensor etc. so as to generate a video signal. As the rectilinear light beam generating device, a micromirror device in which micromirror elements are arranged in a two-dimensional array shape is used. The incident laser beam is converted into a light beam oscillating at a high speed in a certain direction by oscillation of each micromirror element so as to generate a diverging light beam.
