Abstract
A large area optical diagnosis apparatus and the operating method thereof are disclosed. The large area optical diagnosis apparatus includes a light source, a light path structure, and a sensing module. The light source is used to at least emit a coherent light. The light path structure includes a plurality of optical units used for dividing the coherent light into a plurality of first incident lights and a plurality of second incident lights. The plurality of first incident lights are emitted toward an object to be diagnosed and the plurality of second incident lights are emitted toward a reference end. The object to be diagnosed and the reference end reflect the plurality of first incident lights and the plurality of second incident lights to be a plurality of reflected lights. The sensing module senses the plurality of reflected lights to generate a sensing result related to the object to be diagnosed.
