what resolution would be enough on a digital camera to get .09 mill detail in a close up shot about 5 inch away from the camera?

Does it not depend on the field of view (lensing) and the chip (or pixel) size?

Given the resolution requirement, you can figure out how big an FOV you have with a given imaging chip

If you already know the field and the CCD, just divide the field by the number of pixels
