An airborne compact anemometric lidar system includes a laser that can emit a laser beam, an optical system suitable for forming the laser beam emitted by the laser, an optical window that is transparent to the laser radiation emitted by the laser, wherein the lidar system comprises a first prism and a second prism, the first prism being fixed and configured to deflect the laser beam formed by the optical system, the second prism being mounted on a rotation device configured to perform a rotation about the axis of propagation of the laser beam transmitted by the first prism, so that a laser beam deflected by the second prism passes through the optical window by forming, with the normal {right arrow over (n)} to the optical window, a non-zero angle, the angle between the optical axis of the optical system and the normal {right arrow over (n)} being less than 10, the rotation device being driven by a circuit that makes it possible to orient the second prism so as to select the angle with which the laser beam passes through the window.

A light beam can be steered using a non-mechanical beam steerer structure. For example, a combination of sub-aperture and full-aperture beam steering structures can be used (e.g., corresponding to regions of controlled variation in an index of refraction). The sub-aperture elements can include tapered structures defining a saw-tooth or triangular footprint in the plane in which the in-plane steering is performed. Respective rows of sub-aperture tapered structures can be configured to controllably steer the light beam in the first in-plane direction, wherein at least one row of sub-aperture tapered structures defines a first base region edge that is tipped at a first specified in-plane angle relative to a second base region edge defined by another row. Use of the tipped configuration can simplify a configuration of the beam steerer structure, such as allowing a configuration lacking a compensation plate at the input.

A ladar system can estimate intra-frame motion for an object within a field of view of the ladar system using a tight cluster of ladar pulses. For example, ladar pulses in a cluster can be spaced apart but overlapping with at least one of the other ladar pulses in that cluster at a specified distance in the field of view. A ladar receiver can then process the reflections from the cluster to computer intra-frame motion data, such as intra-frame velocity and intra-frame acceleration for an object.

An optical device detachably disposed on a scanner is provided, including a housing, a first opening, a second opening, a lens module, and a fixing member.

The light leaving the housing through the second opening can fall on a scanned object.

A beam control apparatus consists of an electromagnetic field control component, which has a spherical cavity encircled by a transparent spherical shell, and a beam directing component which is spherical in shape and located in the spherical cavity. The two components can rotate relative to each other. A clearance between the two components could be filled with lubricant. The beam directing component has a magnetic moment or an electric dipole moment. A controller controls a magnetic field or an electric field in the spherical cavity of the electromagnetic field control component to exert a torque on the beam directing component to control a direction of the beam directing component, thereby controlling a direction of an emergent beam.
