A scanning apparatus providing separate fixed object focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. The resolution of the digitized representation of the scanned original document can be determined independently of the selection of object focal plane.

A scanning apparatus providing separate fixed object focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. The scan carriage is suspended along an axis substantially parallel to a scan line of a scanned original document and passing through a point substantially coincident with the scan line, thereby minimizing variations in lighting conditions due to vibration of the scan carriage.

An infrared video camera system comprises an uncooled infrared sensor mounted and a thermally conductive thin walled radiation shield for shielding radiation from reaching an active surface of the uncooled infrared sensor. A TEC maintains the sensor active surface and the radiation shield at a substantially constant temperature. The uncooled infrared sensor and radiation shield are further housed in a hollow thermally conductive vacuum cover which is vacuum sealed with a base assembly and includes a vacuum sealed infrared transparent window in an aperture at a top end of the vacuum cover for allowing infrared radiation to reach the active surface and for forming a vacuum chamber enclosing the infrared sensor and radiation shield. A relay optical cell mounted to a camera body comprises at least one optical element for relaying an image formed at its entrance onto the active surface. An imaging optical assembly is interchangeably mounted to the relay optical cell and comprises at least one optical element for imaging an infrared scene to be imaged onto the entrance aperture of the relay cell.

A scanning apparatus providing separate fixed object focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of a single optical element within the scan carriage. The illumination source comprises a single lamp disposed for correct illumination of the selected object focal plane. Automatic resolution selection and focusing of the original image can occur using a converging device comprising a first and second focusing lens.

A scanning apparatus providing separate fixed object focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. A dark slide provides protection against flare during scanning, and can be closed to provide for dark current calibration as well as to seal the system from dust when not in use.
