Abstract: An imaging (e.g., lithographic) apparatus for generating an elongated concentrated scan image on an imaging surface of a scan structure (e.g., a drum cylinder) that moves in a process (cross-scan) direction. The apparatus includes a spatial light modulator having a two-dimensional array of light modulating elements for modulating a two-dimensional light field in response to predetermined scan image data, and an anamorphic optical system is used to anamorphically image and concentrate the modulated light onto an elongated imaging region defined on the imaging surface. To avoid smearing, movement of the imaging surface is synchronized by an image position controller with the modulated states of the light modulating elements such that image features of the scan image are scrolled (moved in the cross-scan direction) at the same rate as the cross-scan movement of the imaging surface, whereby the features remain coincident with the same portion of the imaging surface.

Abstract: An apparatus for correcting a scranning beam produced by a polygonal mirror tilting in small surface segments in each mirror surface segment caused by uneven mirror surfaces of the polygonal mirror. Data indicative of the amount of tilting in each of the surface segments is stored in a memory, which is addressed by a data signal indicative of the present scanning position of the polygonal mirror. Output data from the memory is applied to an acousto-optical modulator disposed in the beam path between the light source and the polygonal mirror.

Abstract: A beam deflection system is provided with electrical circuitry for adaptively correcting the deflection of a beam of radiant energy in a scanning system incorporating a rotating scanning mirror to compensate for misalignment in facets of the mirror. With the use of an acousto-optic modulator providing a deflected beam at an angle dependent on the frequency of an acoustic drive signal, the orientation of the beam can be altered to compensate for the misaligned facets by varying the acoustic frequency. A sensor and bridge circuit signal the position of a beam scan. A memory stores the value of the frequency for scans by each facet, the value being altered with each scan to optimize the frequency. A drift compensation circuit provides for an averaging of the parameter values, and provides a voltage to adjust the balance of the bridge to drive the average value towards a reference value.
