ILLUMINATION LIGHT SHAPING FOR A DEPTH CAMERA |
摘要 |
Various embodiments of a time-of-flight (TOF) depth camera and methods for projecting illumination light into an image environment are disclosed. One example embodiment of a TOF depth camera includes a light source configured to generate coherent light; a first optical stage including an array of periodically-arranged lens elements positioned to receive at least a portion of the coherent light and to form divergent light; a second optical stage positioned to receive at least a portion of the divergent light and to reduce an intensity of one or more diffraction artifacts in the divergent light to form illumination light for projection into an illumination environment; and an image sensor configured to detect at least a portion of return illumination light reflected from the illumination environment. |
