If the external mirror is tilted by an angle of α, the diffraction images of in-phase mode exactly coincide with the apertures, while out-of-phase mode is imaged exactly in between the apertures, resulting in high loss.

最后采用Z/2腔对LD阵列的外腔锁相进行了实验研究，并在外腔镜不偏转和偏转角度α时分别观察到同相模和异相模的锁相现象。

The diffraction distributions of Gaussian beam limited by the circular apertures with different sizes in scanning objectives focal plane were studied, and then the effective spot radius in focal plane was calculated using second moment and compared with the ideal one. The influence of apertures with different sizes on resolution was analyzed.

在不同孔径圆孔的限制下，对扫描物镜焦面上的衍射光场分布进行数值计算，并利用二阶矩统计的方法对焦面上的等效光斑半径进行数值计算，将其与不受限时的理想情况进行对比，分析孔径尺度对激光束扫描系统分辨率的影响。

The merit of the invention are: 1 adopting free curved surface imaging method , three part reflection type Zernike polynomial free curved surface forms short focal distance bigger, relative apertures bigger fields of view angle imaging , rectifying optical aberration much better and its structure is simple; 2 adopting the reflection structure without optical lens, has removed the effect of various chromatic aberration , guarantee the imaging articulation; 3 adopt the design of short focal distance big fields of view angle, focal distance 8 - 15 mm, field of view angles 100 -135 degree, having 120 times multiplications under 250 mm imaging distance, having ultra-thin characteristic property; 4 adopting big relative apertures design ,the relative aperture is 2.0-2.4, having improved the illuminance of flat surface; 5 adopting image space telecentric imaging method , ensures that the image surface irradiance is homogeneous.

本发明的优点是：1采用自由曲面成像方法，三片反射式Zernike多项式自由曲面形成短焦距大相对孔径大视场角成像，更好地校正像差，结构简单；2采用无透镜形式的反射式结构，消除了各种色差影响，保证成像清晰度；3采用短焦距大视场角设计，焦距8～15mm，具有100～135度的视场角，在250mm成像距离下有120倍的放大倍数，具有超薄特性；4采用大相对孔径设计，相对孔径为2.0～2.4，提高像平面上的光照度；5采用像方远心成像方法，保证像面辐照度均匀。
