Uniform lighting device for linear scanning photoelectronic imaging

The invention discloses a uniform lighting device for linear scanning photoelectronic imaging, and relates to the technical field of photoelectronic imaging. The uniform lighting device comprises a diffuse reflector, an integrating sphere light source and an optical fiber light guide assembly. The diffuse reflector is cylindrical as a whole; the inner wall surface of the diffuse reflector comprises a peripheral side surface, a first end surface and a second end surface; the peripheral side surface is provided with a strip-shaped light outlet and a strip-shaped light inlet; the strip-shaped light outlet and the strip-shaped light inlet extend from the first end surface to the second end surface in the axial direction of the diffuse reflector; and the strip-shaped light inlet is located on the side of the strip-shaped light outlet. The integrating sphere light source is mounted on the diffuse reflector and is provided with a light output port. The optical fiber light guide assembly is provided with a light inle
