Abstract (en)
[origin: WO2022189094A1] The invention relates to an optical system for obtaining 3D spatial information within a spatial region, in particular for detecting 3D information regarding an object, comprising: - a light receiving device (110) comprising at least one light detector which can be or is oriented towards the spatial region; - an optical modulator unit (106) for rotating a polarisation of light passing through the modulator unit (106); and - at least one polarisation filter (111) which is situated optically downstream of the modulator unit; wherein at least one bandpass filter is provided which is situated optically downstream of the polarisation filter and/or wherein the modulator unit comprises at least two optical modulators.
