<p>Simple, economical hardware based on incoherent space-frequency analysis overcomes many drawbacks associated with coherent optical systems. We have adopted this technique in developing a compact camera unit that uses a liquid-crystal light modulator for data input. This optically addressable camera system can automate a variety of visual inspection tasks. Adapted to conventional microscopes, it also enables automatic inspection of biological specimen textures, a useful tool in disease detection.</p>
