1. An device for scanning an image of an object, comprising: a controlled transparency film configured to control the passage of light therethrough; and a plurality of detectors configured to measure light passing through the controlled transparency film, wherein the controlled transparency film is modulated to apply a series of filters on the light passing through to the detectors, and the light detectors are sampled in accordance with the application of the filters, such that the samples of measured light represent transform coefficients of the scanned image of the object.
