| Zusammenfassung: | The invention relates to a linear laser which comprises a light source, and a collimating element, a cylindrical mirror and a Powell prism which are sequentially arranged along the light path direction of the light source. The light source is used for emitting light. The collimating element is used for collimating the light to form a collimated light beam. The cylindrical mirror is used for adjusting the slow axis size of the collimated light beam to form a linear light beam, and the Powell prism can move relative to the cylindrical mirror to change the distance between the cylindrical mirror and the Powell prism so as to control the field angle and the uniformity of the linear light beam output by the Powell prism. That is to say, according to the linear laser disclosed by the invention, the field angle and uniformity of the linear light beam output by the Powell prism can be adjusted by changing the distance between the cylindrical mirror and the Powell prism, so that the distance can be changed according t |
