Abstract
An example scanner device includes a sealed enclosure including a scan window to allow light to enter the sealed enclosure, and an optical assembly including a light source and an image sensor. The light source is to emit light through the scan window onto a medium to be scanned. The image sensor is to capture light reflected by the medium through the scan window. The optical assembly is rotatably positioned within the sealed enclosure. An actuator is disposed within the sealed enclosure to rotate the optical assembly to aim the optical assembly at different locations on the scan window.
Claims15
A scanner device comprising:
- a sealed enclosure including a scan window to allow light to enter the sealed enclosure;
- an optical assembly including a light source and an image sensor, the light source to emit light through the scan window onto a medium to be scanned, the image sensor to capture light reflected by the medium through the scan window, the optical assembly rotatably positioned within the sealed enclosure;
- and
- an actuator disposed within the sealed enclosure to rotate the optical assembly to aim the optical assembly at different locations on the scan window.
A scanner device comprising:
- a sealed enclosure including a scan window to allow light to enter the sealed enclosure;
- an optical assembly including a light source and an image sensor, the light source to emit light along a light path that terminates at the image sensor, the light path to pass through the scan window and reflect from a medium to be scanned, wherein the optical assembly is rotatably actuatable within the sealed enclosure to aim the light path;
- and
- a processor coupled to the optical assembly, the processor to control the image sensor to aim the light path at a first location and to capture light from the light path through the scan window as a calibration signal, the processor to rotate the optical assembly to aim the light path at a second location to capture light from the light path through the scan window.
A scanner device comprising:
- a sealed enclosure including a scan window to allow light to enter the sealed enclosure;
- a contact image sensor to illuminate a medium to be scanned through the scan window, the contact image sensor to capture light reflected by the medium through the scan window via a rod lens array, the contact image sensor rotatably positioned within the sealed enclosure;
- a calibration strip disposed outside the sealed enclosure;
- and
- an actuator to rotate the contact image sensor to aim the contact image sensor at different locations on the calibration strip to provide different scan lines at the calibration strip.
