Abstract

The invention relates to an optical module and electronic equipment including the above optical module. The above-mentioned optical module includes a substrate, a mask layer and a light source. The substrate has a light incident surface. The photomask layer is arranged on the light incident surface, and the photomask layer is provided with a plurality of diffraction slits to form a light incident area, and the geometric center of the light incident area points to the In the direction of the edge, the area of ​​the diffraction slit decreases gradually. The light source has a light emitting surface, the light source is arranged on the light incident surface and is spaced from the light incident area, and the light emitting surface is arranged away from the light incident surface. The size of the above-mentioned optical module is small, which can meet the requirements of miniaturization design of electronic equipment, and has good imaging quality at the same time.

Description

technical field [0001] The invention relates to the technical field of virtual imaging, in particular to an optical module and electronic equipment. Background technique [0002] In virtual imaging electronic devices such as virtual reality (Virtual Reality, referred to as VR) equipment, augmented reality (Augmented Reality, referred to as AR) equipment, and mediated reality (Mediated Reality, referred to as MR) equipment, it is usually necessary to configure an eye tracking module. To track the movement of human eyeballs, and change the position and angle of the image according to the movement of human eyeballs, so as to make people feel immersive. However, the current eye tracking module usually needs to be equipped with a light source and a lens group. The light source emits light to the human eyeball, and the lens group processes the light reflected from the human eyeball. Requirements for the miniaturization design of electronic equipment. Contents of the invention ...
