In one embodiment, an apparatus for scanning a beam of light in a digital image recorder includes a curved writing surface translating in at least one direction relative to a stationary frame, a rotatable shaft having a first reflective surface not translating in the at least one direction relative to the stationary frame, and a light source emitting a beam of light directed to the reflective surface for reflection to the curved writing surface.

Scanning a beam of light in a digital image recorder

The present invention relates to an optical system for an apparatus for multi-part differential particle discrimination to facilitate analysis, classification, and sorting of various fluid components for presentation. The optical system is characterized by one or more of the following: a synchronized illumination beam and flow cell conduit, a flow cell arrangement to control back reflection, and light sensor arrangement to particularly gather a specific range of light scatter, such specific range of light scatter directly corresponding to at least one type of particle capable of being identified by the apparatus.

The digital laser image recorder includes a data manipulation and control system which may provide digital data to a digital light source for conversion to an analog modulated light beam. A scanner may also be provided to direct the light beam toward a writing surface which may be disposed on the interior of a rotatable cylinder. A film handling device operable to deliver sheet film to the writing surface may also deliver sheet film from the writing surface to an associated output tray after writing. In another embodiment, beam shaping optics may be provided to convert the analog modulated light beams to collimated beams of a predetermined size and circular distribution. The beam shaping optics may also incorporate a power control filter to control the intensity of the collimated beams. In yet another embodiment, a shutter may be provided. The shutter may have a reflective surface with a first position in which the shutter reflects the light beams away from the scanner, and a second position in which the light beams strike the scanner. A photodiode may also be provided to measure the intensity of the reflected light beams. In still another embodiment, focusing optics may be provided to focus the collimated beams to form laser beams which may be directed toward the scanner.

An apparatus for visualizing image data comprises a first projector (,) and a second projector (,). The first projector (,) is positioned with a first optical axis perpendicular to an image focal plane (,), and projects to the focal plane (,) a first image (A) with a first image area. The second projector (,) is positioned in relative alignment with the first projector (,), with a second optical axis perpendicular to the focal plane (,). The second projector (,) projects to the focal plane (,) a second image (B) with a second image area adjacent to the first image area. A method for visualizing image data comprises projecting to an image focal plane (,) a first image (A) with a first image area, and a second image (B) with a second image area. The first image area is adjusted to be juxtaposed to the second image area.
