摘要： There is provided a System and method of wavefront compensation in a synthetic aperture imaging system. A return signal data représentative of a signal reflected by a target area to be imaged is received. A compensation phase figure corresponding to a wavefront compensation to be applied is provided. The compensation phase figure is added or otherwise applied to the phase pattern of the return signal data in order to obtain a compensated phase pattern. An optical beam is spatially modulated according to the compensated phase pattern to produce a modulated optical beam such that the compensation phase figure produces a wavefront compensation on the optical beam. An image of the target area is optically generated using the modulated optical beam.

摘要： There is described a terahertz (THz) imaging device and method for imaging an object hidden underneath clothing. The THz imaging device is generally configured for illuminating a region of clothing with a THz illumination beam, collecting a return optical beam reflected from the region of clothing in response to the illumination, generating a THz image based on the collected return optical beam, and tracking a position and orientation of the THz imaging device as the THz image is generated. A plurality of complementary THz images are generated by repeating the steps of illuminating, collecting, generating and tracking for a plurality of points of view of the THz imaging device relative to the clothing. By registering these THz images to one another in a common coordinate system based on the tracked position and orientation, the THz imaging device can output a composite THz image representing the hidden object, if any.

摘要： An imaging system that includes an image sensor and imaging optics is provided. The image sensor has a sensing surface and it captures images of a scene. The imaging optics is optically coupled to the image sensor and is configured to form the images of the scene onto the sensing surface of the image sensor. The imaging optics includes a sensor-adjacent optical element having an exit surface located in close proximity to the sensing surface of the image sensor. The exit surface of the sensor-adjacent optical element and the sensing surface of the image sensor are spaced apart by a gap having a gap width enabling evanescent-wave coupling from the exit surface to the sensing surface for light having wavelengths within the sensor spectral range.
