Embodiment Construction
[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] The projectile landing coordinate testing method based on the laser original reflective light curtain of the present invention, such as figure 1 As shown, first build a test system, including laser 1, linear array CCD camera 2, and original reflective screen 3: Laser 1 uses a Powell prism to expand the beam, resulting in a divergence angle greater than the linear array CCD camera 2's field of view angle and uniform distribution of light intensity The linear laser is projected onto the original reflective screen 3 to form a laser light curtain; a linear array CCD camera 2 is placed near the laser to receive the laser reflected by the original reflective screen. In order to ensure that the light reflected by the original reflective screen 3 can illuminate the lens of the entire line array CCD camera, the light curtain generated by the laser 1 must be ...
