    • A multi-color, multi-pulse laser operating at a number of wavelengths is provided with a like number of cavities to produce a like number of output pulses from a single pumping pulse. The spacing between the pulses is easily controlled by controlling the timing of Q-switches, each in a different cavity, so that information is imparted by the pulse spacing. In a two color embodiment, a beam splitting device is positioned along the longitudinal axis of the laser medium to produce two beams which are directed into different cavity resonators, each tuned to a different wavelength. Reflecting surfaces positioned at the end of each cavity redirect each beam back to the beam splitting device where the beams are spatially recombined and subsequently two pulses, one of one color and the other of the second color, are sequentially coupled out of the laser system. The colors may be sufficiently close in wavelength such that detection does not discriminate against the two colors, and a double pulse output is obtained at the detector. In this manner, the laser system produces two output pulses from a single laser medium and a single pumping pulse. The pulse width of each of the pulses may also be controlled by pulse stretching means in one or more of the optical paths.
    • 在多个波长上操作的多色多脉冲激光器具有相同数量的空腔,以从单个泵浦脉冲产生相似数量的输出脉冲。 通过控制Q开关的定时,可以容易地控制脉冲之间的间隔,每个定时在不同的空腔中,以便通过脉冲间隔赋予信息。 在双色实施例中,分束装置沿着激光介质的纵向轴线定位,以产生被引导到不同腔谐振器中的两个光束,每个调谐到不同的波长。 位于每个空腔末端的反射表面将每个光束重定向回分束装置,其中光束在空间上重新组合,随后两个脉冲(一种颜色和另一种颜色之一)被依次耦合到激光系统外。 颜色可以在波长上足够接近,使得检测不区分两种颜色,并且在检测器处获得双脉冲输出。 以这种方式,激光系统从单个激光介质和单个泵浦脉冲产生两个输出脉冲。 每个脉冲的脉冲宽度也可以通过一个或多个光路中的脉冲拉伸装置来控制。

    • A binocular mountable on a headgear, includes two optical systems, one for each eye of the user. Each system includes at least an objective lens and an eyelens. The binocular is pivotably attached to the headgear. When the headgear is in position on the user's head, the objective lenses and the eye lenses can be quickly swiveled out of the way to facilitate free and unaided vision, and returned to the position of binocular-aided vision. The binocular optical systems can be configured to provide either telescopic or microscopic effects. Moreover, the mounts of the lenses are transparent and integrally formed with the respective lenses. Thus, a continuity of visual field without "tunnel" vision is achieved. Hook and loop type fasteners can be used to attach the optical systems to the headgear, which can be either a cap or a visor. Additionally, a laser light/sun light shield can be provided. The optical systems can define bifocal optical systems. A single optical system (i.e., for one eye of the user) can also be mounted to a headgear.
    • 双头安装在头饰上的双目镜包括两个光学系统,一个用于每个用户的眼睛。 每个系统至少包括物镜和眼睛。 双目可枢转地连接到头饰上。 当头带在用户头部的位置时,物镜和眼睛镜片可以快速地摆放出来,以便于自由和无人看守的视觉,并返回到双目视觉的位置。 双目光学系统可以被配置为提供伸缩或微观效果。 此外,透镜的安装是透明的并且与各个透镜一体地形成。 因此,实现了没有“隧道”视觉的视野的连续性。 钩和环式紧固件可用于将光学系统连接到头帽上,头帽可以是帽子或面罩。 另外,可以提供激光/太阳光屏蔽。 光学系统可以定义双焦光学系统。 单个光学系统(即,用于用户的一只眼睛)也可以安装到头饰。
