Fourier Optics Experiment Kit 

Instruction

The experimental system consists of two experiments, that is, the addition and subtraction of optical images. The sinusoidal grating is used as the spatial filter to realize the image addition and subtraction. The optical image differential mainly introduces the spatial differential processing of the image by using the optical correlation method, thus depicting the contour edge of the image. This kind of image processing and the use of a positive projection device of the optical projection class can be used to correct the image pictures.

Experiments

1.Through experiments, the concepts of spatial frequency, spatial spectrum and spatial filtering in Fourier optics are understood.

2.To understand the optical filtering technology, to observe the filtering effect of various optical filters, and to deepen the understanding of the basic ideas of optical information processing.

3.To deepen the understanding of convolution theory.

4.To understand the pseudo color encoding of the ISO density of black and white images
