摘要： Method/system locate external articles using source, detector (PSD), entrance aperture, and magnifying/reducing afocal element—expanding FOR>90°, or refining precision. Between (1) source or detector and (2) aperture, at least one plural-axis-rotatable mirror addresses source/detector throughout FOR. ½- to 15-centimeter mirror enables ˜25 to ˜45 μradian beam divergence. Aperture, afocal element, and mirror(s) define source-detector path. Mirror(s) rotate in refractory- (or air/magnetic-) bearing mount; or mirror array. Auxiliary optics illuminate mirror back, monitoring return to measure (null-balance feedback) angle. To optimize imaging, auxiliary radiation propagates via splitters toward array (paralleling measurement paths), then focusing on imaging detector. Focal quality is developed as a PSF, optimized vs. angle; stored results later recover optima. Mirror drive uses magnet(s) on mirror(s). “Piston” motion yields in-phase wavefronts, so array dimensions set diffraction limit. Also: destructive reply; scaling optimizes acceleration vs. thickness; passive systems.

摘要： The mirror has a base, inner stage, reflector, controller, and mechanical subsystems pivotally supporting stage and reflector: subsystem #1, the stage (about one rotation axis, relative to the base); subsystem #2, the reflector (about another axis, relative to the stage). Stage and reflector each rotate on respective jewel, ceramic or other refractory bearings. Controller establishes stage/base and reflector/stage angles. Subsystems include respective bearings. The method includes (1) using the two-axis mechanism to receive, and measure an incident angle of, incident rays from an external object; (2) then using that mechanism to direct a radiation beam from a laser source toward the external object, responsive to incident rays. Optionally step (1) operates the mirror at peak acceleration, or minimum response time, as function of mirror thickness; and provides two- to three-millimeter mirror thickness. Optionally step (2) directs the beam to disrupt object function or impair object structure.

摘要： Plural image planes are illuminated through a single image-collecting objective system. The field of view or magnification (or both), is allocated dynamically among the plural planes. Preferably the planes include two detector planes—one corresponding to a wide field of view (FOV) and the other to a steerable narrow one. Allocation is performed by a beam splitter in combination with a steering mirror, or steering-mirror array, that steers both fields together. The splitter isolates radiation corresponding to the narrow FOV from radiation corresponding to the wide FOV. In method forms of the invention, an electrooptical observation system produces simultaneous plural images for a region of interest. The system displays simultaneous images having respective plural resolutions. In operation a first, relatively wider FOV continuously covers a region of interest; while the second is narrower and has finer resolution than the first.

摘要： Selected scene regions are imaged. IMAGING CHANNEL: mirrors (preferably MEMS) address an imaging sensor to regions. CALIBRATION CHANNEL: the mirrors direct radiation from a source to a calibration sensor, along an imaging-channel segment. Beam splitter(s) let the channels share optical path at the mirrors. To minimize imaging-channel diffractive blur, the calibration channel modifies wavefront angle and smoothness at the mirrors—measuring (and setting mirrors to optimize) PSF sharpness, then applying these measurements (and settings) to optimize imaging-channel settings by iterative multidimensional gradient search. An afocal lens receives scene radiation, magnifying deflection at the scene. An FOR is imaged on the imaging sensor; the mirrors address the sensor to a narrow FOV within the FOR; the lens enlarges deflections to cover the FOR. Plural diffraction-grating orders communicate between calibration source and sensor when the selected region is in plural scene portions, regardless which FOV is addressed.

摘要： Separate reception/transmission apertures enhance pointing: reception is more efficient than transmission (kept smaller for MEMS steering). Apparatus aspects of the invention include lidar transmitters emitting laser beams, and scan mirrors (or assemblies) angularly adjustable to deflect the beams in orthogonal directions. In one aspect, afocal optics magnify deflection; a transmitter aperture transmits the beam; a lidar receiver doesn't share the transmitter aperture. In another aspect, auxiliary optics calibrate the deflection.A method aspect of the invention notices and responds to a remote source—using a similar local laser, adjustable scan mirror or assembly, afocal deflection magnifier, transmission aperture and separate receiver. Method steps include operating the receiver to notice and determine location of the remote source; and controlling the transmitter to direct laser light back toward that location.Among preferences: receiver aperture exceeds five times transmitter aperture; receiver is segmented; beam expander between laser and mirror(s) controls waist or divergence, for selecting Gaussian or Rayleigh divergence and “zoom”.

摘要： A light beam is detected/localized by multisector detector—quad-cell, or 5+ sectors handling plural beams. Preferences: Beams focus to diffraction limit on the detector, which reveals origin direction by null-balance—shifting spots to a central sector junction, and measuring shifts to reach there. One or more MEMS reflectors, and control system with programmed processor(s), sequence the spot toward center: following a normal to an intersector boundary; then along the boundary. One afocal optic amplifies MEMS deflections; another sends beams to imaging optics. After it's known which sector received a spot, and the beam shifts, source direction is reported. The system can respond toward that (or a related) direction. It can illuminate objects, generating beams reflectively. Optics define an FOR in which to search; other optics define an FOV (narrower), for imaging spots onto the detector. The FOR:FOV angular ratio is on order of ten—roughly 180:20°, or 120:10°.

摘要： A detector and aperture determine radiation characteristics, including angular direction throughout a specified range, of external articles. Preferably an afocal aperture element enlarges/reduces the article and volume FOR. Mirror(s) along a path between detector and aperture, rotatable about plural axes, make the detector address varying regions. Preferably each mirror is MEMS, exceeding five to thirty microns. The detector “sees” articles throughout the range, at constant magnification. Other aspects rotate magnetically controlled dual-axis MEMS mirrors, each with electrical coils opposed across an axis, and anther magnet whose field interacts with coil-current fields, generating force components: one includes oppositely directed forces, torquing the mirrors; another thrusts mirrors outward from the array rest plane, causing variable “piston”. Alternatively, other forces pull mirror(s) outward—and the second component attracts them inward. Components are adjusted to steer a beam in a desired direction, and wavefronts from adjacent mirrors are in phase for finer diffraction limit.
