Abstract
A scanner including first and second light monitor elements and a light redirection system operable in a first mode to focus light reflected from a scanned object and the first light monitor element onto a sensor and operable in a second mode to focus light reflected from the object and the second light monitor element onto the sensor. The light monitor elements are arranged such that the first light monitor element will not interfere with scans in the second mode, which may be a high resolution scan mode, and the second light monitor element will not interfere with scans in the first mode, which may be a normal resolution scan mode.
Claims13
A scanner for scanning an object, comprising:
- first and second light monitor elements;
- and
- a scanning system including
- a sensor,
- a light source adapted to direct light onto the object and onto the first and second light monitor elements such that light is reflected from the object and first and second light monitor elements, and
- a light redirection system operable in a first mode to focus light reflected from the object and the first light monitor element onto the sensor and operable in a second mode to focus light reflected from the object and the second light monitor element onto the sensor.
A scanner for scanning an object in a scan direction, comprising:
- a housing including a window;
- first and second light monitor elements associated with the window and offset from one another in the scan direction;
- and
- a scanning system including a sensor, the scanning system being operable in a first mode to focus a region of the object and the first light monitor element onto the sensor and operable in a second mode to focus a region of the object and the second light monitor element onto the sensor.
