1. An inspection system, comprising: a hybrid sensor that comprises: a monochromatic portion that is arranged to obtain a monochromatic image of a first area of an object; a multiple-color portion that is arranged to obtain a multi-colored image of a second area of the object; wherein the monochromatic portion comprises monochromatic sensing elements that sense radiation of a same frequency band; wherein the multiple-color portion comprises color sensing elements of different types, wherein different types of color sensing elements are associated with different frequency bands; a storage element arranged to store the monochromatic image and the multiple-color image; and a defect detection module arranged to detect defects by processing at least one of the monochromatic image and the multiple-color image.
