Abstract
The present invention provides a method for performing high dynamic range low inter-pixel spatial and wavelength crosstalk optical image detection in a camera comprising an Optical Array Device (OAD), a point Photo Detector (PD) and a Photo Detector Array (PDA) sensor. The method comprises imaging incident light from an object onto an image plane of the Optical Array Device (OAD) to form an incident image map; selecting by the OAD and the Point Photo Detector and by the OAD and the Photo Detector Array a plurality of pixels on the incident image map for time-frequency coding; time-frequency coding the selected pixels by the OAD; detecting by the point PD the optical irradiance values of the time-frequency coded pixels output from the OAD; and performing signal processing on the detected optical irradiance values to determine the light intensity of each of the selected pixels.
