    • Systems and methods are provided for focus recovery of multi-channel images. Control circuitry of an imaging system can restore an image by removing image blurring introduced by the lens, sensor noise introduced by the sensor, and a signal offset between multiple channels of the image. In some embodiments, the control circuitry can calculate one or more estimates of a signal offset of multiple observed signals. Using statistics generated from offset-removed signals, the control circuitry can generate one or more recovery kernels which can be applied to offset-removed signals to generate recovered signals. In other embodiments, instead of explicitly removing a signal offset from each observed signal, the control circuitry can implicitly remove the signal offset when calculating the first and second order statistics of one or more observed signals.
    • 提供系统和方法用于多通道图像的聚焦恢复。 成像系统的控制电路可以通过去除透镜引入的图像模糊,由传感器引入的传感器噪声以及图像的多个通道之间的信号偏移来恢复图像。 在一些实施例中,控制电路可以计算多个观察信号的信号偏移的一个或多个估计。 使用由偏移去除信号产生的统计量,控制电路可以产生一个或多个恢复内核,其可应用于偏移消除的信号以产生恢复的信号。 在其他实施例中,当计算一个或多个观测信号的第一和第二阶数统计时,控制电路可以隐含地去除信号偏移。

    • The present invention provides a method to effectively inhibit the oxidization of VO(acac)2 in solution for months. It is believed that VO(acac)2 forms a π-complex with as many as three allylic alcohols which precludes reaction with any oxygen in the system. Although saturated and homo-allylic alcohols were also tested, this effect appears only in the allylic-alcohol based solutions. This ability to inhibit oxidation of VO(acac)2 allows these solutions to be used for making thermochromic VO2 film much more easily and economically as it avoids the requirement of operating under low oxygen level conditions. Thus the present invention provides a method of stabilizing vanadium oxyacetylacetonate (VO(acac)2) in solution against oxidation for extended periods of time, comprising the steps of mixing the oxyacetylacetonate precursor in an allylic alcohol prior to spin-coating for VO2 film formation. The allylic alcohol may be β-methallyl alcohol. Alternatively, the allylic alcohol may be any one of 4-buten-2-ol, 2-buten-1-ol, 1-penten-3-ol, 2-hexen-1-ol and 1-hexen-3-ol.
    • 本发明提供一种在溶液中有效抑制VO(acac)2氧化数月的方法。 据信,VO(acac)2形成具有多达三个烯丙醇的复合物,其排除与系统中的任何氧反应。 虽然也测试了饱和和均烯醇,但这种影响仅出现在基于烯丙基醇的溶液中。 这种抑制VO(acac)2氧化的能力使得这些溶液可以用于制备热变色VO2膜,因为它避免了在低氧水平条件下运行的要求。 因此,本发明提供了一种在溶液中稳定钒氧乙酰丙酮化钒(VO(acac)2)的方法,以防止长时间的氧化,包括在旋涂之前将氧乙酰丙酮酸前体混合在烯丙醇中以进行VO2膜形成的步骤。 烯丙醇可以是α-甲基丙烯醇。 或者,烯丙醇可以是4-丁烯-2-醇,2-丁烯-1-醇,1-戊烯-3-醇,2-己烯-1-醇和1-己烯-3-醇中的任一种。
