    • A system and method of controlling laser power output levels includes a laser (9) and a control circuit (27) for energizing the laser. A sensor (11) that measures power output from a back facet of a laser element (17) of the laser provides feedback to the control circuit so as to maintain power output from the laser constant. The back facet of the laser element is covered with a coating that has transmission and reflection characteristics that are relatively insensitive to minor changes in the wavelength of the laser. The coating is preferably a thin metallic layer which provides a constant and adequate reflectivity and low transmittance. With the specific metallic layer on the back facet, the transmittance remains relatively consistent even when there is a change in wavelength. This provides for consistent readings at the sensor.
    • 控制激光功率输出电平的系统和方法包括用于激励激光器的激光器(9)和控制电路(27)。 测量从激光元件(17)的背面输出功率的传感器(11)向控制电路提供反馈,以保持激光器的功率输出恒定。 激光元件的背面覆盖有具有对激光波长的微小变化相对不敏感的透射和反射特性的涂层。 涂层优选是提供恒定且足够的反射率和低透射率的薄金属层。 利用背面上的特定金属层,即使当波长发生变化时,透射率也保持相对一致。 这提供了传感器上一致的读数。

    • A method of making a panoramic image includes capturing a first image (30) defining a first overlap region (115) capturing a second image (40), and defining a second overlap region (215). Two points (150, 151) in the first overlap region are identified and a first vector (175) overlap region connecting the two points is defined. Two points (250, 251) in the second overlap region which correspond to the two points in the first overlap region are identified and a second vector (275) the two points is defined. If points in the first vector match points in the second vector, determine if the first and second vectors are parallel. If the vectors are not parallel, rotate the second vector image until the second vector is parallel to the first vector.
    • 制作全景图像的方法包括捕获限定捕获第二图像(40)的第一重叠区域(115)并限定第二重叠区域(215)的第一图像(30)。 识别第一重叠区域中的两个点(150,151),并且定义连接两个点的第一向量(175)重叠区域。 识别与第一重叠区域中的两个点对应的第二重叠区域中的两个点(250,251),并且定义两个点的第二向量(275)。 如果第一个矢量中的点与第二个矢量中的点匹配,则确定第一个和第二个矢量是否是平行的。 如果矢量不平行,则旋转第二矢量图像直到第二矢量平行于第一矢量。
