Abstract:
There is provided a miniaturized optical system including a protection cover, a light source, an image sensor and at least one interference film. The protection cover has a first surface and a second surface. The light source and the image sensor are disposed opposite to the first surface of the protection cover. The interference film is disposed between the light source and the protection cover to allow the light source to form a predetermined light shape in front of the second surface of the protection cover and/or disposed between the image sensor and the protection cover to allow the image sensor to receive light of a predetermined range in front of the second surface of the protection cover.
