An illustrative example detector (20) for use on a vehicle (22) includes a radiation emitter (30) having a near field region that is defined at least in part by a wavelength of radiation emitted by the radiation emitter. A radiation steering device includes a plurality of reflectors (32), an actuator (40), and a controller (42). The reflectors (32) are situated to reflect the radiation emitted by the radiation emitter (30). The reflectors (32) are in the near field region and have at least one characteristic that limits any phase shift of the reflected radiation. The actuator (40)is configured to adjust an orientation of the reflectors (32). The controller (42) is configured to determine an orientation of the plurality of reflectors (32) relative to the radiation emitter (30) to steer the emitted radiation reflected from the reflectors (32) in a determined direction. The controller (42) is configured to control the actuator (42) to achieve the determined orientation.
