A diagnostic equipment having an auto-focusing function comprising a image detection device, a first scanning device, a mobile optical lens assembly, a focusing detection device and a first splitter assembly is provided. The image detection device comprises a first light source and a first photo detector. The first light source provides a first incident light and the first incident light incident to an object and becomes a first signal light. The first photo detector is for receiving the first signal light. The first scanning device is for adjusting a path of the first incident light and to scan the object. The mobile optical lens assembly has a lens and a mobile platform. The first splitter assembly is for transmitting the first and the second signal light to the first and the second photo detector, respectively.

Auto-focusing diagnostic equipment

An optical apparatus for adjusting the position and aperture of a pinhole and a method using the same are provided. A light beam is provided. The light beam is focused on an object and reacts with the object to form a signal beam. The signal beam is focused and projected on a liquid-crystal switch. The projection position of the signal beam on the liquid-crystal switch is determined, and the transparence of the liquid-crystal switch at the projection position is adjusted to form a transparent area. The signal beam passes through the transparent area and reaches a light detecting unit to form a detecting signal. The aperture of the transparent area is adjusted according to the intensity of the detecting signal. The liquid-crystal switch is driven to move, so that the position of the transparent area in the moving direction of the signal beam is adjusted.
