Abstract: In one arrangement, a system includes a light source to provide outgoing light having at least one time-varying attribute at a selected one of multiple wavelength channels, the at least one time-varying attribute including either/both of (a) a time-varying intensity profile and (b) a time-varying frequency deviation, a beam director to spatially direct the outgoing light into one of multiple directions in two dimensions into an environment having a spatial profile, the one of the multiple directions corresponding to the selected wavelength channel, a light receiver to receive at least part of the outgoing light reflected by the environment, and a processing unit to determine at least one characteristic associated with the at least one time-varying attribute of the reflected light at the selected one of the multiple wavelengths for estimation of the spatial profile of the environment associated with the corresponding one of the multiple directions.

Abstract: Described herein is a system for directing light over two dimensions. In a first embodiment, an optical beam director includes a wavelength router, such as an optical interleaver, optically coupled to an array of dispersive elements, such as free-space diffractive couplers. In a second embodiment, an optical beam director includes a diffractive element optically coupled to a 1D-to-2D spatial interleaver.

Abstract: Various forms of optical circulator are disclosed. The optical circulators act on polarisation of the light to direct light between its ports. Also disclosed are systems and methods for facilitating estimation of a spatial profile of an environment based on a light detection and ranging (LiDAR) based technique. The systems and method may include or use one or more of the various forms of optical circulator. In one arrangement, the present disclosure facilitates spatial profile estimation based on directing light over one dimension, such as along the vertical direction. In another arrangement, by further directing the one-dimensionally directed light in another dimension, such as along the horizontal direction, the present disclosure facilitates spatial profile estimation based on directing light in two dimensions.
