WebMar 1, 2001 · For PDT of acne vulgaris, incoherent light sources may be more advantageous than laser because they are cheaper and produce uniform skin‐surface illumination of large areas. Laser equipment is much more expensive than PDT using incoherent light. Furthermore, we think that polychromatic visible light may be superior to 630‐nm laser … WebCoded aperture imaging (CAI) methods offer multidimensional and multispectral imaging capabilities with minimal resources than what is needed in a lens-based direct imager. In the CAI method, the light diffracted from an object is modulated by a coded mask, and the resulting intensity distribution is recorded.

As a result, the captured image is a sum of four different blurred images. Two of the images are simply blurred by the incoherent PSF from the two point sources in the Michelson interferometry setup. The other two images are blurred by the CSF.
