Abstract: An optical imaging method using a single-pixel detector, An image of a target object is expressed by using discrete pixels, and the size of the image is M×N pixels. A cosine structured light field generator is used for generating a series of light fields that have different frequencies and are distributed according to cosine, wherein each set of frequencies corresponds to at least three different initial phase ? values; the light fields with cosine distribution that have different frequencies and different initial phases are used to sequentially irradiate the target object; an optical detector (2) is used for sequentially receiving light intensity signals from the target object and then response values of the optical detector (2) are sequentially collected and recorded; An image reconstruction algorithm is established on the basis of the light fields, the number of measurements can be greatly reduced, and a high-quality reconstructed image can be obtained.
