filter grating

The design of the film-systems used for bio-fluorescence excitation and barrier filters were discussed in this paper.

本文论述生物荧光激发滤光片及栅滤光片的膜系设计。

Two parallactic films of a nature color scene are obtained with a three color grating camera.

本文采用两种方法来制真彩色体视全息图:一种是用三色光栅照相机拍摄景物的两张视差照片,然后用单色激光器经二次曝光全息记录制成一张真彩色体视全息图,在普通白炽灯照明下可再现真彩色体视全息像。

With this method, 2D encoded photographs are taken first with a tricolor grating camera and then decoded with a 4f optical system w.

用三色光栅对彩色景物编码,4f光学系统进行彩色解码,并在光路中加上光栅进一步调制物光束,使用散射参考光,对景物的系列编码片做顺序记录,合成一张真彩色动感立体全息图。

Using tricolor grating, the color image is encoded to a gray level image, thus the three channels of R, G, and B are transformed into a single channel.

根据白光信息处理原理,利用三色光栅对原始彩色图像进行编码,将R、G、B三个通道的彩色信息转换为灰度信息,彩色图像被编码为一幅灰度图像,从而使彩色图像的R、G、B三个通道合成为一个通道;再将此灰度图像作为待加密图像,采用双随机相位加密技术将其加密为稳定的白噪声,由此实现了彩色图像的单通道加密。

According to tricolor grating theory, a color image is encoded into a gray scale image, and then the gray scale image is encrypted by double-phase encoding.

在该方法中,首先采用三色光栅编码原理将一幅彩色图像编码为一幅灰度图像,再利用双随机相位加密技术对其加密,从而实现了彩色图像的单通道加密。
