摘要：

An optical Haar mother wavelet is created with a Semetex 128 x 128 magneto-optic spatial light modulator. Two techniques for dilating the mother wavelet are explored: (1) aperture stopping and (2) operating the SLM in ternary phase-amplitude mode. Discrete resolution levels of a continuous wavelet transform are obtained by optically correlating a binarized image with multiple dilations of the mother wavelet. Frequency-plane masks for the correlation process are generated using thermoplastic holography. Experimental results are compared with a digital simulation of the wavelet transform.
