Abstract
Compact holographic heads using the spot size detection of double beams with linear photodetector-elements are proposed to attain highly reliable performances under considerable optical misalignment. Acceptable amount of misalignment could be expanded by a factor of ten compared with that in an astigmatic system. Mechanical accuracy of the integrated head is also discussed.
