Abstract

The invention relates to a computing associated imaging method via a mobile phone, and belongs to the field of optical image application. According to the method, a computing associated imaging application in the mobile phone starts a speckle pattern processing module, the speckle pattern processing module generates a speckle pattern, the speckle pattern is displayed in an LCD screen, and the speckle pattern irradiates a target object via the LCD screen; the computing associated imaging application starts a light intensity signal detection and imaging module when the speckle pattern is displayed in the LCD screen; the light intensity signal detection and imaging module calls a front camera to detect a speckle image reflected by the target object; the light intensity signal detection and imaging module carries out association computing on the speckle pattern that is irradiated on the target object by the LCD screen and speckle image data obtained by the front camera; and via associatedcomputing, the image of the target object is reconstructed and displayed in the LCD screen. The computing associated imaging technology is tightly combined with imaging equipment of the mobile phone,and the imaging effect of mobile equipment in the special environment is enhanced.

Description

technical field [0001] The invention belongs to the field of optical imaging applications, and in particular relates to a method for realizing calculation-associated imaging by using a mobile phone. Background technique [0002] Correlation imaging, also known as ghost imaging, is an emerging optical imaging technology in recent years. Traditional optical imaging schemes generally use the detector to directly record the intensity of reflected or transmitted light after passing through the target object, and use the intensity and phase of the light field to obtain information about the target object, that is, to use the first-order correlation property of the light field for imaging, thus imaging Detection is inseparable from the object; unlike traditional imaging methods, correlation imaging does not directly use the light information reflected or transmitted by the object to image, but uses the high-order correlation characteristics of the light field to image the object, t...
