主 题:single-pixel imaging array spatial light field measurable speckle gradation
摘 要:The array spatial light field is an effective means for improving imaging speed in single-pixel ***,distinguishing the intensity values of each sub-light field in the array spatial light field requires the help of the array detector or the time-consuming deep-learning *** at this problem,we propose measurable speckle gradation Hadamard single-pixel imaging(MSG-HSI),which makes most of the refresh mechanism of the device generate the Hadamard speckle patterns and the high sampling rate of the bucket detector and is capable of measuring the light intensity fluctuation of the array spatial light field only by a simple bucket *** numerical and experimental results indicate that data acquisition in MSG-HSI is 4 times faster than in traditional Hadamard single-pixel ***,imaging quality in MSG-HSI can be further improved by image stitching *** approach may open a new perspective for single-pixel imaging to improve imaging speed.
