1. A portable handheld system, comprising:
- an illumination component as part of an integral unit that directs electromagnetic radiation of a predetermined wavelength at a target associated with a material of interest, and which electromagnetic radiation causes a change in the electromagnetic radiation wavelength to occur when in contact with the material of interest;
a sensor component as part of the integral unit that senses the change in the electromagnetic radiation wavelength as change data;
an image processing component as part of the integral unit that receives the change data and creates images of the change data for analysis;
a change detection component as part of the integral unit that receives the images, analyzes the images to determine a type of the material of interest, and outputs the type as type information; and
a presentation component as part of the integral unit that displays the type information for visual perception by a user.

Abstract
An illumination and detection architecture that illuminates a target for detecting a material of interest. The architecture includes an illumination component that illuminates the target using a predetermined light wavelength known to energize and thereby cause a detectable change in the desired chemical and/or compounds associated with the target in a particular way. The change is then captured by an image capture system and processed to determine the presence or absence detected of the desired material of interest at the target.

15. A computer-implemented method of determining a material of interest associated with a target, comprising:
-
illuminating a target from a handheld unit using electromagnetic radiation of a predetermined wavelength to identify a material of interest; sensing a changed wavelength of the electromagnetic radiation as change data when the electromagnetic radiation impinges on the material of interest creating an image of the change data; analyzing the change data via the image; detecting a type of the material of interest based on analysis of the change data; outputting the type as type information to a display; and presenting the type information for viewing. - View Dependent Claims (16, 17, 18, 19, 20)
