Extended depth of field with absolute position detection in multi-wavelength digital holography
, 2022 We present a novel approach for detecting the absolute position of surfaces in multi-wavelength holography. We extent the depth of field from ~0.08 mm to ~3 mm and get the absolute position with accuracies better than 10 ...
