The invention relates to a single particle fuel micro-combustion, gasification suspension, ignition, imaging and detection system. At present, common fuels used for microenergy systems based on micro-combustion are gas fuels which are difficult to store and carry. The system provided by the invention comprises a first laser driver, a first laser, a second laser driver, a second laser, a first reflection lens, a first spectroscope, an inverted telescope, a second spectroscope, a high-power objective lens, microparticle fuels, a micro-combustion chip, a three-dimensional electric displacement platform, a condensing lens, a third spectroscope, an iris diaphragm, a collecting lens, an optical source, a first lens, an optical filter, a four-quadrant detector, a second lens, a third spectroscope, a CCD (Charge Coupled Device) camera, a second reflection lens and an infrared camera. The all-optical particle suspension positioning, igniting and testing method is utilized to test the micro-combustion and the gasification of particles in a non-interference manner, so that the facticity of the micro-combustion and the gasification can be best reflected, the essence of the particles is restored and the mechanism of the particles is effectively revealed.
