A high-speed video system is disclosed that includes a moving image absorbing disk at an image plane. The disk has a pattern that passes and blocks image data. The disk is located between an event and an image sensor, or reflects an image to the image sensor. The disk is rotated at a speed that matches the desired reconstructed image frame rate. The image sensor frame data is processed using image reconstruction techniques, such as the D-AMP or TWIST algorithm, to recover a time sequence of reconstructed images. Additional images can be reconstructed for each image sensor frame if some spatial resolution is sacrificed. For continuous video, the disk speed is adjusted to the sensor frame rate. For burst mode, a single sensor image is acquired and a short image sequence is reconstructed. This image capture system works with a variety of radiations, including infrared, light, UV and X-rays.
