It's M2 factor is approaching the ideal value 1 and the beam intensity profile remains Gauss Profile. Laser beam with good propagation and focus characters. The beam can propagate a long way and can be focused with lens with long focal distance. The focal beam waist radius is 134μm, the focal distanced of the focus lens is 300mm. It's focal depth is about 5mm and the focal shift is about 1mm in the range of processing (3m).

结果表明，Slab CO2激光器具有高光束质量，其M2因子非常接近1的理想值；激光束具有良好的传输和聚焦性能，可以长距离传输；使用焦距为300mm的聚焦镜聚焦，聚焦光斑的束腰半径约为134μm，光束横截面能量分布接近理想的高斯分布，焦深约为5mm，在加工范围内(3m)，激光束的焦点漂移量大约为1mm。

So the technique of uncooled microbolometer infrared imaging has become one of the main points from now on. In the paper uncooled microbolometer infrared imaging system is studied from focal plane character, image dealing and application. The details are in the following: On uncooled microbolometer infrared focal plane aspect: first, the work principle of microbolometer, manufacturing technology of microbolometer infrared focal plane, temperature balance equation of microbolometer detector are analyzed. The performance of microbolometer detector is predicted by model. Second, the infrared focal plane is the core of infrared system, whose quality can determine the performance of the system. It is the precondition that the high quality of every detective unit maintains the qualification of the focal plane. The even degree of detective units has great influence on imaging characters if the other characters of detective units are normal.

本文以非致冷微测辐射热计红外成像系统为对象，从焦平面特性、图像处理和红外系统应用方面展开分析、研究，具体内容如下；在微测辐射热计红外焦平面方面，首先分析了微测辐射热计的工作原理、微测辐射热计红外焦平面的工艺制作、微测辐射热计探测单元的温度平衡方程，根据有关参数对其特性进行建模预测；其次，红外焦平面是红外系统的核心，它的质量的好坏直接决定系统性能，因此保证其各探测单元的高性能是维护焦平面品质的前提，在探测单元其它特性正常的情况下，各探测单元之间特性的均匀程度对系统成像性能有极大影响，为此本文提出自适应滤波多项式焦平面非均匀性校正算法从软件角度解决焦平面的固有的噪声问题。

The laser beam emitted by the laser is expanded to the cutting width required by the tipping paper via the laser beam expanding system, the expanded laser beam passes through the cylindrical surface focusing mirror and 4 focuses on the focal plane form a focal line and the tipping paper is cut off by the focal line on the focal plane.

由激光器发出的激光束经激光扩束系统将激光束扩大至水松纸所需的切割宽度，经扩束后的激光束通过柱面聚焦镜，在焦平面4聚焦形成一条聚焦线，水松纸在焦平面上被此条激光聚焦线割断。
