IMAGE CAPTURING APPARATUS
First Claim
1. A image capturing apparatus, comprising:
- a cover plate;
a light source;
a sensor, disposed next to the light source, wherein the light source and the sensor are located on the same side of the cover plate; and
a collimator, disposed between the cover plate and the sensor and comprising a plurality of collimating elements overlapping with each other, wherein each of the collimating elements comprises a transparent substrate and a light absorbing layer disposed on the transparent substrate, the light absorbing layer comprises a plurality of light passing openings, the light passing openings expose a plurality of sensing areas of the sensor, spacing between the light passing openings is S, a width of each of the light passing openings is W, and W<
S, and a transparent substrate thickness of a first collimating element in the collimating elements is T1, a transparent substrate thickness of a second collimating element in the collimating elements is T2, and the image capturing apparatus satisfies;

Abstract
An image capturing apparatus including a cover plate, a light source, a sensor, and a collimator is provided. The light source and the sensor are located on the same side of the cover plate. The collimator is disposed between the cover plate and the sensor, and the collimator includes collimating elements overlapping with each other. Each collimating element includes a transparent substrate and a light absorbing layer disposed on the transparent substrate. The light absorbing layer includes a plurality of light passing openings. The light passing openings expose sensing areas of the sensor. Spacing between the light passing openings is S. A width of each light passing opening is W, and W<S. A transparent substrate thickness of a first collimating element in the collimating elements is T1. A transparent substrate thickness of a second collimating element in the collimating elements is T2. The image capturing apparatus satisfies:
