Abstract
A scanner configured to provide different patterns of light for scanning is provided. The scanner may include electrochromic surfaces and reflective surfaces, which can be arranged and used to direct light through different pathways within the scanner. The scanner may further include one or more light emitting components, receiving optics, and power supplies to facilitate generating the different patterns of light for scanning. A method of scanning is also provided.
Claims20
A scanner, comprising:
- a housing having an opening;
- a receiving optic;
- a light emitting component configured to selectively emit light;
- a first electrochromic surface, the light emitting component oriented such that the light emitted from the light emitting component is at least partially directed towards the first electrochromic surface;
- and
- a power supply coupled to the first electrochromic surface,
- wherein the receiving optic, the light emitting component, and the first electrochromic surface are at least partially enclosed within the housing, and
- wherein the receiving optic is oriented towards the opening.
5 more elements
A scanner configured to provide variable illumination, the scanner comprising:
- a housing having an opening, the housing having enclosed at least partially therein:
- a receiving optic oriented towards the opening,
- a plurality of light emitting components configured to selectively emit light,
- a first plurality of electrochromic surfaces, each electrochromic surface of the first plurality of electrochromic surfaces oriented to receive at least a portion of the light from a respective light emitting component of the plurality of light emitting components;
- and
- at least one power supply coupled to the plurality of light emitting components and to the first plurality of electrochromic surfaces.

A scanning method, comprising:
- providing a scanner comprising at least:
- a housing having an opening;
- a receiving optic oriented towards the opening,
- a light emitting component configured to selectively emit light,
- a first electrochromic surface, the light emitting component oriented such that the light emitted from the light emitting component is at least partially directed towards the first electrochromic surface, and
- a power supply coupled to the first electrochromic surface and configured to selectively provide a first voltage to the first electrochromic surface,
- wherein the receiving optic, the light emitting component, and the first electrochromic surface are at least partially enclosed within the housing;
- providing the first voltage to the first electrochromic surface to provide reflectivity from the first electrochromic surface;
- while the first voltage is applied, emitting the light from the light emitting component;
- and
- reflecting the light off of at least the first electrochromic surface to generate a first light pattern for scanning.
