A method and a system for single-shot multi-frame ultrafast terahertz imaging of a scene, the method comprising generating a pump beam and a probe beam: generating a THz beam from the pump beam and passing the THz beam through the scene: multiplexing the probe beam in the time domain and in the spatial-frequency domain. yielding a multiplexed probe beam; detecting a THz beam passing through the scene: guiding the multiplexed probe beam to a THz detection crystal and converting the multiplexed probe beam into mutually orthogonal linear polarized beams: guiding the mutually orthogonal linear polarized beams to a camera: and recovering frames of the scene from multiplexed images acquired by the camera.

Compressed ultrafast photography (CUP) techniques that produce spatially encoded images from a first series of images where each spatially encoded image has first and second views of an image of the first series of images superimposed with a pseudo-random binary spatial pattern, that transform the first view and/or the second view such that the first view is rotated 180 relative to second view, that deflect each spatially encoded image by a temporal deflection distance that varies as a function of time-of-arrival, and that integrate the spatially encoded images into a CUP image.

An image pickup apparatus being capable of performing a photometry process under a suitable condition and of achieving high-speed continuous photographing. A first drive, which accumulates and reads an electric charge with an image sensor for a photometry process, and a second drive, which accumulates and reads an electric charge to obtain an image signal for a static image, are alternately repeated during continuous photographing. A photometry process is performed based on the electric charge read by the first drive. An aperture value for obtaining the image signal of an (N+1)th frame is calculated based on a result of the photometry process during accumulation for obtaining the image signal of an N-th frame. A control unit controls a diaphragm based on the calculated aperture value and a predetermined aperture value during reading of the electric charge for obtaining the image signal of the N-th frame.

In some embodiments, a plurality of images is captured through an image sensor of a camera during a period of time. The plurality of images is registered to calculate an image-sensor-based measure of movement of the camera during the period of time. The image-sensor-based measure of movement is compared to a motion-sensor-based measure of movement of the camera during the period of time, and a systematic offset between the motion-sensor-based measure of movement and the image-sensor-based measure of movement is calculated.

A carrier configured to carry an imaging device. The carrier may include a frame assembly comprising at least two frames, a combined rotation about the at least two frames controlling an orientation of the imaging device, or compensating the movement or vibration to stabilize the imaging device. The carrier may also include a motor assembly comprising at least two motors, each motor configured to drive a corresponding frame to rotate, wherein at least one angle formed by two frames among the at least two frames is a non-right angle.

High-definition particle detection during centrifugation of a pharmaceutical liquid is provided. Centrifugation of fluid containers drives particles to the interior surface of the container if the particles are denser than the fluid and to the middle of the container if the particles are less dense than the fluid. The imager can then be focused directly on the particle itself for rapid identification without the need for computing complex particle trajectories. If the centrifugation of the container is carried out at an angle to the axis of symmetry of the container, particles can be driven to a single line on the interior surface of the container by the centrifugal force, making the identification of the particles even more straightforward than in two dimensions. The particle imager can also be attached to the rotating container to prevent blurring of the particle image due to the relative motion of the container and imager.
