Wavefront coding system is a new type of opticaldigital twostep imaging system. The cubic phase mask is used to get asymmetric point spread function and the intermediate blurred image which nearly the same in a considerable depth of field. Combined with spatial domain optical imaging modeland kronecker product, an image restoration algorithm which based on the BiCGSTAB(BiConjugate Gradient Stabilized) and antireflective boundary conditions was used in the digital decoding part of the wavefront coding system. This algorithm have advantages such as small computing amount, high computing speed and nearly no boundary effect. The new algorithm was optimized and transplanted with the characteristics of parallel computing for the platform of TMS320DM642.The whole platform consists of image capture module, image display module and external memory module. By a specially designed optical system, the experiment imaging the human and object with the object distance of 1 m, 5 m and 10 m. From the experimental result of middle blurred images, the effect of this new algorithm on the platform of TMS320DM642 is good, and it gives the possibility to realization of the truly portable and practical of the wavefront coding system.
