    摘要： An optical processor is presented for applying optical processing to a light field passing through a predetermined imaging lens unit. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. The pattern is configured to define a phase coder, and a dispersion profile coder. The phase coder affects profiles of Through Focus Modulation Transfer Function (TFMTF) for different wavelength components of the light field in accordance with a predetermined profile of an extended depth of focusing to be obtained by the imaging lens unit. The dispersion profile coder is configured in accordance with the imaging lens unit and the predetermined profile of the extended depth of focusing to provide a predetermined overlapping between said TFMTF profiles within said predetermined profile of the extended depth of focusing.

    摘要翻译： 光学处理器用于将光学处理应用于通过预定成像透镜单元的光场。 光学处理器包括具有不同光学特性的间隔开的区域形式的图案。 该模式被配置为定义相位编码器和分散轮廓编码器。 相位编码器根据由成像透镜单元获得的扩大聚焦深度的预定轮廓，影响针对光场的不同波长分量的透焦调制传递函数（TFMTF）的轮廓。 色散曲线编码器根据成像透镜单元和扩大的聚焦深度的预定轮廓来配置，以在扩展的聚焦深度的所述预定轮廓内提供所述TFMTF轮廓之间的预定重叠。
