The illumination unit includes a broadband pulsed light source, and a spectrometer configured to divide a single pulse of light, which has been emitted from the broadband pulsed light source, into a plurality of wavelengths and to produce a time lag between each two adjacent ones of the plurality of wavelengths.

Disclosed are a camera and an object processing apparatus using the same. A camera according to an embodiment of the present invention focuses on moving objects by adjusting the ray distance between a lens and a sensor in a manner whereby a mirror is moved between the lens and the sensor, which are each fixedly installed, or whereby one side end of the sensor is moved, without a mirror.

A quick release mechanism includes a rotating member, a slider, and a screw connecting the slider with the rotating member. The rotating member is configured to be arranged on a first side of a first gimbal support frame of a gimbal. The slider is configured to be arranged on a second side of the first gimbal support frame that is opposite to the first side, and between the first gimbal support frame and a second gimbal support frame of the gimbal. The screw is configured to penetrate the first gimbal support frame, drive the slider to move in a first direction to abut between the first gimbal support frame and the second gimbal support frame, and drive the slider to move in a second direction opposite to the first direction to be released from the first gimbal support frame and the second gimbal support frame.

A container that will house components of the device will be mounted to railroad ties to permit the user of this device to gather high resolution images of the undercarriage of a moving train car as it passes over a container that houses certain components of the system. The speed of the camera shutter will be dictated by the software that will work in conjunction with a linear speed detection device. The gathered images can be reassembled and forwarded to a remote location. The software provides an alarm in the event of a present danger.

Disclosed is ultrafast photographing apparatus based on polarization-time mapping, which can obtain spatiotemporal (x, y, t) information of a dynamic scene by means of single exposure. The apparatus includes an active illumination system, a synchronous control system, a data acquisition system, and a data reconstruction system. Firstly, illumination light is generated by the active illumination system to irradiate on a dynamic scene; the synchronous control system is configured to control the single exposure of a camera; the data acquisition system is configured to acquire a two-dimensional image containing sixteen frames of spatiotemporal aliasing by means of polarization modulation and polarization filtering; and the data reconstruction system is configured to reconstruct the acquired image by using an iterative Tikhonov regularization algorithm, and finally to restore sixteen frames of original dynamic scenes with time series information.

A 3-axis camera gimbal is disclosed in the present disclosure. The disclosure gimbal may include: a first supporting body; a lens barrel including a lens group and coupled to the first supporting body in a rotatable manner about a first axis; a rolling driving unit mounted at a first position of the lens barrel to provide force for rotating the lens group about a second axis perpendicular to the first axis; a pitching driving unit mounted to the first supporting body to provide force for rotating the lens barrel about the first axis; a second supporting body coupled to the first supporting body in a rotatable manner about a third axis perpendicular each of to the first and second axes; and a yawing driving unit mounted to the second supporting body to allow the first supporting body to rotate about the third axis. Various embodiments are also possible.

The present disclosure claims an apparatus, a method and a system for the calibration of a streak camera. A plurality of fiber optic cables is bundled together such that the input ends and the output ends of the fibers are grouped together. Each fiber in the bundle has a distinct and characteristic time taken for light to traverse from the input end to the output end known by the observer. This characteristic time depends on the physical and optical properties of the fibers selected. Calibration light is collected by the fiber input face and travels through the individual fibers in a characteristic time. Individual light pulses will subsequently be detected by the streak camera which converts the time profile of the incoming light pulses into a spatial profile. An observer can compare the observed spatial separation profile to an expected spatial separation profile for calibration.

Methods and systems for imaging a target. In some examples, a system includes an optical modulator configured for applying, at each time of an exposure window, a respective optical modulation pattern to a received image of the target to output a modulated image. The system includes a camera configured for capturing a single image frame for the exposure window by receiving, at each of time, the modulated image of the target. The system includes a demodulator implemented on a computer system and configured for demodulating the single image frame based on the optical modulation patterns to recover a number of recovered image frames each depicting the target at a respective recovered time within the exposure window.
