Disclosed are a device and a method of depth sensing that handle light leakage issues. In some embodiments, the depth sensing device includes a light emitter that illuminates an environment of the depth sensing device. The device identifies a first portion of the emitted light that is prevented from reaching the environment of the device due to being redirected by an optical component located in proximity to the light emitter. An imaging sensor of the device detects a second portion of the emitted light that reaches and is reflected by a surface in the environment of the device other than a surface of the optical component. The device generates, based on the second portion of the emitted light, a depth map that includes a plurality of values corresponding to distances relative to the device, wherein said generating excludes from consideration the identified first portion of the emitted light.
