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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The system of claim 1, wherein the illumination component includes a laser unit that emits a beam of electromagnetic radiation of a predetermined wavelength at the target, and which electromagnetic radiation causes the change in the electromagnetic radiation wavelength to occur when in contact with the material of interest. ### Claim 3 (depends on 1) The system of claim 1, further comprising a geolocation component as part of the integral unit that provides location information as to location of the unit. ### Claim 4 (depends on 1) The system of claim 1, wherein the material of interest is associated with at least one of an atmospherically suspended or surface absorbed energetic nitrocompound, hazardous material, or drug. ### Claim 5 (depends on 1) The system of claim 1, wherein the integral unit is employed in combination a viewer through which a user views the target, and the presentation component displays a user-identifiable indication on the viewer that the material of interest is present or not present at the target. ### Claim 6 (depends on 1) The system of claim 1, wherein the illumination component illuminates the target with a range of electromagnetic radiation wavelengths to determine presence of multiple different types of materials of interest. ### Claim 7 (depends on 1) The system of claim 1, wherein the components of the integral unit operate to ultimately display the type information under low light and nighttime conditions. ### Claim 8 (depends on 1) The system of claim 1, wherein the illumination component disperses the electromagnetic radiation of a single wavelength over an area that includes the target to detect the material of interest in the area or a range of electromagnetic radiation having different wavelengths over the area that includes the target to detect correspondingly different materials of interest in the area. ### Claim 9 (depends on 1) The system of claim 1, wherein the integral unit is temporarily or destructively disabled, locally or from a remote location. ### Claim 10 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;
