The invention belongs to the field of optical imaging and particularly relates to a combustion particle image acquisition device and method, aiming at mainly solving the problem that a particle shape and a flame frontal surface cannot be distinguished in a combustion particle imaging process, and obtaining high-quality combustion particle and flame images. The device comprises a laser active light source, an expanded beam lens, a collimation lens, an attenuation sheet, a combustion particle placement platform, an optical filter and a camera. The laser active light source provided by the invention is used for illuminating, and the optical filter guarantees the passing of reflecting light of a wave band of the laser active light source and is used for an acquisition method of images photographed by the camera matched with the wave band of the laser active light source, so that a clear particle combustion image is obtained; the method is simple and easy to operate; the acquired image has high quality and less background noises; the difficulty that particles and flame form bright spots in a passive detection process is overcome; and in the obtained image, the particle shape and the flame frontal surface in the obtained image are clear and have a good distinction degree, and the success rate and accuracy of dividing the particles and flame can be improved.
