摘要： The disclosure is directed to an apparatus and method for obtaining an improved moire fringe pattern image of an object. A beam of incoherent light is projected at the object. A grating is disposed in the path of the beam projected at the object, this grating being referred to as a projection grating. Means are provided for focusing the beam reflected from the object to obtain an image at an image plane. Another movable grating is disposed at the image plane. This movable grating is referred to as a reference grating. Means are provided for recording the image at the image plane, the recording means being, for example, a photographic or video camera. In accordance with an important feature of the invention, means are provided for moving the projection grating and the reference grating in synchronism. In a preferred embodiment, the projection and reference gratings are mounted in spaced relation in a movable member, and the synchronized motion of the gratings is implemented by moving the member. In a form of the disclosure, a double-projection set-up is used wherein two projection beams are directed at the object through first and second movable projection gratings, respectively. In this embodiment, the first and second projection gratings are moved in synchronism with the reference grating. This is preferably achieved by mounting the three gratings in appropriate spaced relationship in a common member, and moving the member.

摘要： A display device utilizes a plurality of pixels arranged in a predetermined configuration for recording and displaying information. Each pixel includes a substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitoning between a first and a second state in response to a heater element. The light modulating material in the first state causes destructive interference in the predetermined wave length of light and in the second state causes constructive interference in the predetermined wave length of light. The pixel structure is buried within an aerogel thereby minimizing the heat dissipation rate from the pixels.

摘要： A display device utilizes a plurality of pixels arranged in a predetermined configuration for recording and displaying information. Each pixel includes a substrate and a light modulating material for selectively modulating a predetermined wave length of light by transitioning between a first and a second state in response to a heater element. The light modulating material in the first state causes destructive interference in the predetermined wave length of light and in the second state causes constructive interference in the predetermined wave length of light. The pixel structure is buried within an aerogel thereby minimizing the heat dissipation rate from the pixels.

摘要： A display device is disclosed including a plurality of pixels arranged in a predetermined configuration. Each pixel including a mirror element disposed over a flat surface. A light modulating material disposed over the mirror element for selectively modulating a predetermined wave length of light received from an external source by transitioning between a first and a second state. The light modulating material in the first state causes destructive interference in the predetermined wave length of light and in the second state causes constructive interference in the predetermined wave length of light.
