1. A system for direct imaging and diagnosing of abnormal cells in a target tissue, comprising: a disposable optical speculum; an image acquisition system having the speculum assembled on and mechanically secured thereto, the image acquisition system arranged to capture at least one of a single image or multiple images or video of cells within the target tissue using at least one of bright field or dark field ring illumination divided into independently operated segments to obtain a plurality of data sets; and an image analysis and control unit in communication with the image acquisition system, the image analysis and control unit analyzing the data sets and applying algorithms to the data sets for diagnosing abnormal cells; wherein the image acquisition system includes a laser ablation module with a movable mirror system to enable accurate ablation of abnormal cells, wherein the laser ablation module uses the data sets to eliminate the diagnosed abnormal cells, and the image acquisition system is designed to stop ablation when it is detected that abnormal cells no longer exist in the image.
