A system and method are disclosed which enable deposition parameters to be controlled in producing a metal surface to tune the localized surface plasmon resonance (LSPR) wavelength of such metal surface to a desired wavelength. For example, the surface produced may be used as an enhancement surface within a surface-enhanced spectroscopy process, wherein such surface is produced having a LSPR wavelength that provides the maximum extinction of a particular excitation light. In one embodiment, a metal is deposited onto a substrate, while controlling one or more deposition parameters to tailor the LSPR of the resulting metal surface to a desired wavelength. In one embodiment, the substrate is smooth, and does not require a mask prearranged thereon for controlling the LSPR wavelength. Rather, deposition parameters, such as temperature of the substrate, deposition rate, and film thickness may be controlled to effectively tune the LSPR wavelength of the metal surface.

A vehicle ( ) includes an infrared imaging system ( ). The system includes an infrared camera ( ) positioned in the center of the front grille of the vehicle. The infrared camera includes a window ( ) that has a holographic fringe pattern ( ) which cooperates with visible light rays ( ) to generate an image ( ) that is visible at a location spaced from the vehicle. The visible image may, for example, be a trademark or other symbol identifying the manufacturer of the vehicle. Infrared radiation ( ) passes through the element and the structure thereof without significant change, and is detected by an infrared detector ( ). A visible image corresponding to the infrared radiation is ultimately displayed by a head up display ( ) on a portion ( ) of the vehicle windshield ( ).
