Incoherent optical differential pulse code modulation (ODPCM) technique for image information compression
Abstract
The basic principle of using an incoherent optical system to simulate the digital optical differential pulse code modulation (ODPCM) for image compression and the calculation of image compression ratio. The design and development of the optical sampler and the optical interpolator are demonstrated. Some preliminary experimental results on the transmitted, compressed image and the received, restored image of a binary picture, obtained on an incoherent optical setup with a real-time PROM spatial light modulator for baseline subtraction, are reported.
