对脉冲激光全息照相术的发展和应用到记录液体推进火箭的注入与燃烧现象有关的雾滴反应和逆反应做了一定的工作。这一工作包括建立一个适应于记录冷流雾滴和热流燃烧现象的独特的双光束透射式全息摄影机。应用Q开关红宝石激光器作全息摄影机的照相光源。为了证明摄制液体推进燃烧的全息照片的可能性进行了多种试验,这些试验包括记录在火箭发动机的冲击缸内气体点火(起火)和燃烧。冷流全息照相的研究集中于确定这一技术分辨率的可能性和极限。燃烧的研究要确定把全息照相用来雾滴反应现象的可能性。除了对全息照相的研究之外,应用基本全息摄影的试验装置来摄制高质量的激光照明的照片。本工作的结果,首先是成功地记录了大家熟知的液体火箭燃烧现象的大视场角的全息照片。燃烧的全息照片呈现的清晰度接近100微米。冷流全息照相的试验达到的清晰度近似为50微米。这些全息照片的再现的象散极大地降低了清晰度,这归因于先用脉冲红宝石激光器(0.69微米)来记录全息照片,后用连续波氦-氖激光器(0.63微米)来再现全息照片,在波长上相差10％的缘故。
Some work has been done on the development of pulse laser holography and the application of droplet reaction and reverse reaction to the recording of liquid propellant rocket injection and combustion phenomena. This work includes the creation of a unique dual-beam transmission hologram adapted to record cold-flow droplets and heat-flow combustion. Applications Q-switched ruby lasers for holographic cameras. Various experiments were conducted to demonstrate the potential of a liquid for making a fired holographic photograph. These included gas ignition (ignition) and combustion recorded in the impact cylinder of a rocket engine. Cold-flow holographic research has focused on the possibilities and limits for determining the resolution of this technique. Burning studies have to determine the possibility of holographic use for droplet reaction phenomena. In addition to holographic research, basic holographic test equipment was used to produce high quality laser-illuminated photographs. The result of this work is, first of all, the successful holographic recording of a large field of view of the familiar phenomenon of liquid rocket combustion. Burning holograms show sharpness close to 100 microns. Cold-flow holographic tests achieved a sharpness of approximately 50 microns. The astigmatism in the reproduction of these holograms greatly reduced the sharpness due to the holographic recording first with a pulsed ruby laser (0.69 μm) followed by the reproduction of a hologram with a continuous helium-neon laser (0.63 μm) A difference of 10% in the wavelength of the reason.
