Abstract
A portable and potentially computer-controlled aircraft windscreen or the like test arrangement for quantitative determination of haze and energy transmissivity characteristics in the windscreen material. The test arrangement includes two portable transducer enclosures which lend to convenient use in tested aircraft environments and provides optical assistance in achieving a desired alignment of these transducer enclosures prior to testing. Improved sensitivity over prior haze evaluation arrangements is achieved through use of this accurate alignment and through capture of a large fraction of a haze generated optical signal with an efficient transducer configuration. The testing arrangement also includes optical filtering capability and laser signal modulation assistance in excluding ambient illumination interference with measurement-related optical signals. A plurality of use environments are contemplated including military and non-military uses.
