Compression of images is an important application in the field of satellite image processing
as it is suitable for optimization of storage space and sharing over internet with optimum
bandwidth utilization. This study presentsa novel method for compressing satellite imagery
using sinusoidalamplitude grating. The Satellite image is first modulated with high frequency
amplitude grating in a fixed orientation. Therefore, the satellite image is converted into
optical frequency domain. Due to this modulation, three spots (spectrum bands) have been …
