High-precision schlieren system light path adjusting device and use method thereof

The invention discloses a high-precision schlieren system light path adjusting device and a use method thereof, and belongs to the field of power machinery. A high-precision schlieren system light path adjusting device is characterized in that a laser emitter and a laser receiver are horizontally arranged, the laser emitter emits horizontal laser, the laser receiver receives the horizontal laser, and a constant volume bomb is parallel to the horizontal laser; wherein one schlieren instrument, the constant volume bomb, the optical sensor and the other schlieren instrument are sequentially arranged in the direction parallel to the horizontal laser, an incidence window and a perspective window of the constant volume bomb correspond to one schlieren instrument and the optical sensor respectively, the light source irradiates one schlieren instrument, and the camera corresponds to the other schlieren instrument. The signal output end of the optical sensor is connected with the signal input end of the computer. Acco
