SUMMARY
The discussion centers on the impact of pixel size in CCD cameras on observing first-order interference patterns in off-axis digital holography. A CCD camera with 6.7-micrometer pixels successfully captured the first-order interference pattern, while a switch to a 1.67-micrometer pixel camera resulted in the disappearance of this pattern. The likely cause is the smaller overall sensor size of the latter camera, which limited the capture of low spatial frequency information essential for observing the first-order pattern.
