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.
