Title:
COMPLEX AMPLITUDE SENSING IMAGING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/259042
Kind Code:
A1
Abstract:
A complex amplitude sensing imaging device and method. The device comprises: a lensless digital camera (1), a sampling board (2), a connection housing (3), and a processor; the lensless digital camera (1) comprises an image sensor (11); the sampling board (2) is provided in parallel with the image sensor (11); the lensless digital camera (1) and the sampling board (2) are connected by means of the connection housing (3); a lighting area (21) having the same size and shape as the image sensor (11) is provided on the sampling board (2); a plurality of lighting holes (211) are provided in the lighting area (21); the central position of the lighting area (21) is on the same horizontal line as the central position of the image sensor (11). Light passes through an object to irradiate the sampling board (2), and then passes through the lighting holes (21) to be diffracted and propagated to the image sensor (11), the image sensor (11) obtains a light intensity distribution map (I) of the light wave, and then the processor uses the complex amplitude sensing imaging method to obtain a complex amplitude distribution map of the object by means of calculation, thereby realizing holographic imaging of the object. The complex amplitude sensing imaging device and method improve the object imaging accuracy without reference light.
