A remote sensing system includes a transmitter for transmitting an online signal and first and second offline signals toward a target. A receiver receives a returned online signal and first and second returned offline signals from the target. A processor is provided for determining (a) a first ratio based on the returned online signal and first offline signal, and (b) a second ratio based on the returned online signal and second offline signal. A filter is also provided for correlating the first ratio with the second ratio for determining whether the returned online, first offline and/or second offline signals are useable. The returned online, first offline and second offline signals are used to compute first and second concentration path lengths (CPLs) of a column of air between a target and the remote sensing platform.

A method of selectively producing a glossy or matte finish to an ink jet printed image by applying a clear protective plastic laminate having a glossy finish to the surface of the image, heating the laminate to soften it and then selectively impressing a surface texture into the soften laminate. Pressing the softened laminate against an endless belt having a textured surface forms the surface texture. The laminate is maintained in contact with the belt for a cooling period so as to permit a cold separation of the laminate from the belt.

A diode-pumped solid state pulsed laser includes an intracavity nonlinear crystal for wavelength conversion by difference frequency mixing and a secondary resonant cavity containing an additional nonlinear crystal for parametric amplification. Primary and secondary cavities are capable of injection seeding and wavelength stabilization resulting in a very narrow, stable, and well defined spectral output. The combination of pump diode pulsing, the implementation of the intracavity parametric oscillator and parametric amplifier results in very efficient operation. Optical fiber coupled parametric oscillator byproduct light allows simple and non-invasive wavelength diagnostics and monitoring upon connection to an optical spectrum analyzer.

An overcoat application apparatus is used to transfer an overcoat material from a donor to a printed media. The overcoat application apparatus in this case includes a donor supply reel, a donor guide bar, a heated fuser guide, a pressure guide, an overcoat application peel apparatus, and a donor take-up reel. The donor supply reel provides a continuous source of donor plus overcoat material. The donor guide bar guides printed media and the donor plus overcoat into a nip created by forcing the heated fuser guide and pressure guide together. The heated fuser guide is used to transport the printed media and laminate carrying donor through the nip and apply heat to the laminate carrying donor and printed media. The pressure guide is used to apply pressure to the fuser guide in order to produce the mechanical nip. The nip plus the heat causes the overcoat material on the donor to be transferred to the printed media. After the fusing process, the peel bar is used to separate the support layer of the laminate carrying donor from the printed media that is now coated with the overcoat material. The overcoat application peel apparatus has three features that aid in the overall ability to perform the separation of the donor layer from the overcoated printed media. These are the first peel guide, the second peel guide and the take-up platen.
