An imaging system is disclosed that includes an illumination source, a diffractive modulator, imaging optics, and a coherence reduction system. The illumination source is for producing an illumination field. The diffractive modulator is for receiving the at least partially coherent illumination field and producing a modulated illumination field. The imaging optics are for directing the modulated illumination field toward an imaging surface. The coherence of one of the illumination field and the modulated illumination field is reduced.

System for correction of spatial cross-talk and pattern frame effects in imaging systems

The invention relates to an exposure device for exposing a transparent photographic original and reproducing said photographic original ( ) on photosensitive material or by means of a recording device. The exposure device has a primary light source ( ) comprising a number of elements that emit light of different spectral bands, whose light travels to the photographic original along a first optical path or can be directed onto the photographic original using optical elements. The exposure device has additional real and/or virtual light sources, ( ,) whose light strikes the photographic original along additional optical paths, or can be directed onto the photographic original using optical elements. The light that falls along the additional optical paths strikes the photographic original ( ) at different angles of incidence from the angle of incidence of the first optical path.

Exposure device for exposing a transparent photographic original

An imaging system is disclosed that includes an illumination source, a modulator and a variable Fourier diaphragm. The illumination source produces a first illumination field having a first frequency and a second illumination field having a second frequency. The modulator receives the first illumination field and the second illumination field, and produces a first modulated illumination field and a second modulated illumination fields. The variable Fourier diaphragm selectively passes one of the first modulated illumination field and the second modulated illumination field.

System and method for use of dark field fourier diaphragm in multi-frequency imaging

A device and a method for exposure of visual data onto light-sensitive recording material, a light source which emits light in at least one color, and a control unit for regulating the light amount. The control unit is connected to a light measuring unit. The light measuring unit has at least two detectors, which measure at least two different spectral components of the same exposure color. The control unit and the light measuring device form a closed loop control circuit.
