FIG. 1.

Variations in the transmittance and reflectance with the duration of irradiation under a DPSS laser .

Image of FIG. 2.
FIG. 2.

Experimental setup. Lenses 1 and 2 are used to expand a plane wave, and D is a diaphragm. Lenses 3, 4 and 3, 5 are the lenses that transform the transmitted and reflected signals, respectively. The DDCLC sample is placed in the transform plane.

Image of FIG. 3.
FIG. 3.

The object (a grating mask with spacing) is a periodic step function, which yields several diffracted orders following Fourier transformation.

Image of FIG. 4.
FIG. 4.

Transmittance and reflectance of the zeroth, first, and second diffracted orders after the beam through the DDCLC film. The horizontal axis represents the intensity of the zeroth-order beam.

Image of FIG. 5.
FIG. 5.

Transformed images obtained by irradiating the DDCLC spatial filter at (a) , (b) , and (c) .

Image of FIG. 6.
FIG. 6.

Simulated images of the filtering of some orders of spatial frequencies; (eight orders are considered in the Fourier transform): (a) all pass (eight orders); (b) zeroth–first orders transmitted, second–eight orders reflected; and (c) zeroth–second orders transmitted, third–eighth orders reflected.
