We are attempting here at Illinois Wesleyan to create a holographic speckle-pattern inteferometer. We have been working at it for some time and have come to a roadblock in terms of picture quality. We're using a high quality optics table so there are no table vibrations. All of the mounts are tightly and securely mounted. We are using an image multiply system and the standard image-subtraction with Labview. We have an image, but we're looking for other adjustments or suggestions to try to improve our picture. If anyone else is doing similar research we'd extremely appriaciate recommendations for better picture quality.
Follow the link below for the current quality of our efforts. In this image we are driving a metal plate at a resonant frequency of 1542 Hz. This is the best image quality we have right now and to show what we are supposed to see, I have outlined the pattern in red.
