| description | A TOF depth sensing module (300) and image generation method are provided. The TOF depth sensing module (300) includes a light source (310), a polarization filter (320), a beam shaper (330), a first optical element (340), a second optical element (350), a receiving unit (360) and a control unit (370). The light source (310) is configured to generate a beam. The polarization filter (320) is configured to filter the beam to obtain a beam in a single polarization state. The beam shaper (330) is configured to increase a FOV of the beam in the single polarization state to obtain a first beam whose FOV meets a first preset range. The control unit (370) is configured to control the first optical element (340) to control a direction of the first beam to obtain an emergent beam. The control unit (370) is further configured to control the second optical element (350) to deflect, to the receiving unit (360), a reflected beam obtained by reflecting the emergent beam by a target object. In the method, a spatial resolution of a finally obtained depth image of the target object can be improved. |
