*** 9800827 Thurmes This Small Business Innovation Research Phase II project will produce liquid crystals with negative birefringence, and liquid crystal mixtures with negative birefringence dispersion. The negative birefringence materials will be used to optimize liquid crystal mixtures' birefringence for liquid crystal displays. Display fabrication with negative birefringence dispersion liquid crystals will give achromatic displays; that is, displays which are equally transmissive to lights of different wavelengths. There are many immediate ramifications of developing a liquid crystal with negative birefringence dispersion. For instance, liquid crystal shutters will no longer suffer from such severe chromatic disturbances, optical filters will be much more color-balanced and provide more free spectral range, polarization interference filters will need fewer stages and hence be less expensive while transmitting more light, and Fabry-Perot tunable filters can be made using liquid crystal SLMs. The potential commercial applications of the improved performance characteristics described above will include liquid crystal shutters without chromatic disturbances, optical filters with more color balance and more spectral range, polarization interference filters, Fabry-Perot tunable filters. ***

*** 9800827 Thurmes该小企业创新研究二期项目将生产负双折射液晶和负双折射色散液晶混合物。负双折射材料将用于优化液晶显示器中液晶混合物的双折射性能。用负双折射色散液晶制造显示将得到消色差显示；也就是说，显示器对不同波长的光具有相同的透射率。开发具有负双折射色散的液晶有许多直接的分支。例如，液晶快门将不再遭受如此严重的色度干扰，光学滤光片将更加色彩平衡，提供更多的自由光谱范围，偏振干涉滤光片将需要更少的级，因此更便宜，同时透射更多的光，法布里-珀罗可调滤光片可以使用液晶slm。上述改进的性能特征的潜在商业应用将包括无色度干扰的液晶快门、具有更多色彩平衡和更大光谱范围的光学滤光片、偏振干涉滤光片、Fabry-Perot可调滤光片。＊＊＊
