Abstract

The invention relates to an optical module and electronic equipment comprising the optical module. The optical module comprises a substrate, a photomask layer and a light source. The substrate is provided with a light incident surface. The photomask layer is arranged on the light incident surface, a plurality of diffraction slits are formed in the photomask layer to form a light incident area, andthe areas of the diffraction slits are gradually reduced in the direction that the geometric center of the light incident area points to the edge of the light incident area. The light source is provided with a light-emitting face, the light source is arranged on the light-in face and spaced from the light-in area, and the light-emitting face is arranged away from the light-in face. The size of the optical module is small, the requirement for miniaturization design of electronic equipment can be met, and meanwhile good imaging quality is achieved.

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 ...
