During exposure, motion of more than one wavelength of light is permissible between the subject and lens or the lens and the photo-sensitive element.These improvements result from the use of a particular type of angular reflector which is a retro-reflecting sheet.

Abstract: In the formation of microstructures, a preformed sheet of photoresist, such as polymethylmethacrylate (PMMA), which is strain free, may be milled down before or after adherence to a substrate to a desired thickness. The photoresist is patterned by exposure through a mask to radiation, such as X-rays, and developed using a developer to remove the photoresist material which has been rendered susceptible to the developer. Micrometal structures may be formed by electroplating metal into the areas from which the photoresist has been removed. The photoresist itself may form useful microstructures, and can be removed from the substrate by utilizing a release layer between the substrate and the preformed sheet which can be removed by a remover which does not affect the photoresist. Multiple layers of patterned photoresist can be built up to allow complex three dimensional microstructures to be formed.

Abstract: The present invention tunes and stabilizes a volume hologram by migrating an ultraviolet sensitive epoxy resin into the hologram with a solvent, causing the volume hologram to swell and shift its center frequency. When a sufficient shift has occurred, the epoxy resin is exposed to ultraviolet light, setting the resin and preventing further change. An appropriate resin-solvent solution can be arrived at for different media by slowly changing the ratio of solvent to resin and observing the end product until the desired frequency shift and broadbanding is observed with visually or with a spectrometer.
