    摘要： A film transport mechanism moves film from area to area and then stops it to project an image. During the period while the film is being transported, the lens is shuttered and glass flats on either side of the film are opened. This way, the viewer does not see a blurred montage of images being moved across a screen at a high rate of speed, and there is a much less chance of scratching film. The shutter may be either a mechanical blade which cuts across a beam of light or an electrical circuit which dims a light supply to darken the screen. Dimming is preferred to switching a lamp off or on since it is much less damaging to a filament if it remains continuously energized.

    摘要翻译： 电影传输机制将影片从一个区域移动到另一个区域，然后停止投影影像。 在胶片运输期间，镜头被关闭，胶片两侧的玻璃平板打开。 这样，观众看不到以高速率在屏幕上移动的图像的模糊蒙太奇，并且刮擦电影的机会要少得多。 快门可以是切割光束的机械叶片或者使灯光变暗以使屏幕变暗的电路。 将灯关闭或打开时，优选调光，因为如果灯丝保持连续通电，则对灯丝的损坏要小得多。

    摘要： An method of and apparatus (10) for performing laser thermal processing (LTP) of a workpiece (74) having one or more workpiece fields (78). The apparatus includes a pulsed, solid state laser light source (14) having more than 1000 spatial modes (M) and capable of emitting one or more pulses of radiation with a temporal pulse length between 1 nanosecond and 1 microsecond, a workpiece stage (70) for supporting the workpiece, and an illumination optical system having an exposure field (64). The system is arranged between the laser light source and the workpiece stage so as to illuminate within the exposure field at least one of the one or more workpiece fields with the one or more pulses of radiation, with an irradiance uniformity of less than ±5%. The method and apparatus is particularly well-suited for LTP processing of workpieces which require a single pulse or only a few pulses of high-irradiance radiation. Other applications of the present invention include rapid thermal annealing of semiconductor devices in semiconductor device manufacturing and processing, recording information in storage media, and, in general, conditioning surfaces.

    摘要： A light tunnel apparatus (200 or 300) having an output end (56 or 98), for uniformizing light (L) that travels through a light tunnel (30 or 80). The apparatus comprises a light tunnel having first and second sides (36, 40 or 86, 90), and one or more AO modulators (210 or 310) respectively arranged on at least one of the first and second sides. The AO modulators are arranged such that activating the one or more of them causes at least one of the first and second sides to be displaced. This displacement changes the path of light traveling through the light tunnel by an amount sufficient to reduce illumination non-uniformities at the output end. The light tunnel may be a hollow light tunnel (30) with reflective inner surfaces, or a solid light tunnel (80) with a refractive index. A method of uniformizing illumination using a light tunnel is also disclosed.

    摘要： A folded light tunnel apparatus and method of providing light with a high degree of spatial uniformity in a compact arrangement. The light tunnel (100, 190, 300, 350) comprises plurality of prisms (110, 310) having a different cross-sectional dimension (W) and at least one beveled end (110E) having a corresponding beveled end face (110F) through which light reflected by the beveled end passes. The plurality of prisms are arranged adjacent one another in a either two-dimensional or three dimensional stack, with each beveled end face arranged adjacent another beveled end face such that light reflected from one beveled end is received by said adjacent beveled end face and coupled into the adjacent prism. The width of the prisms is governed by a scaling factor (K or K′) that depends on whether the prism stack is two-dimensional or three-dimensional. Designing the light tunnel according to the scaling factor allows for the light tunnel to be theoretically 100% efficient in the transmission of light.

    摘要： An apparatus for correcting aberrations in prisms in convergent light paths. The prism has a transparent entrance and exit face which are connected by a hypotenuse surface. The effect of adding a wedge-shaped addition is made on one of the entrance or exit faces to create a compensating dispersive spectrum to compensate for lateral chromatic aberration. The hypotenuse surface is formed as a spherically convex surface to produce a compensating astigmatic aberration to compensate for the astigmatic aberration caused by the entrance and exit faces of the prism.
