Method and apparatus for providing omnidirectional lighting in a scanning device
First Claim
1. An illumination assembly of a handheld scanning device comprising:
- a first passive light pipe terminating in an angled tip;
a second passive light pipe terminating in a square tip;
a first illuminator that is aligned with the first passive light pipe wherein the first passive light pipe transmits light from the first illuminator to an area of interest;
a second illuminator that is aligned with the second passive light pipe wherein the second passive light pipe transmits light from the second illuminator to the area of interest; and
wherein at least one of the first or second light pipes are removably mounted to a body section of the handheld scanning device.

Abstract
Systems and methods are provided for selectively controlling the illumination, and particularly dark field illumination, applied to a symbol to be decoded, and for determining a suitable or optimized level of lighting for decoding the symbol. A method includes providing a light source comprising a plurality of individually-controllable lighting elements for providing low angle dark field illumination; activating an image sensor for detecting image data reflected from an encoded data symbol when the encoded data symbol is illuminated by the light source; and providing a controller connected to each of the individually-controllable lighting elements, the controller being programmed for: selectively activating the individually-controllable lighting elements to vary the direction of the low angle dark field illumination provided by the light source; and processing the image data detected by the image.
