Choice of best modulator operating conditions for photometric photoelectric microscopes and autocollimators

Conclusions

  1. 1.

    The formulas allow one to determine the optimal slit width and scan amplitude for a given system, which can provide sensitivities higher by 5.4–22.4% than those derived from the previously accepted optimal relation between these parameters as derived without allowance for diffraction.

  2. 2.

    The calculated points have only a small spread around the approximating straight lines, so (10) and (11) can be used for wide ranges in image width.

  3. 3.

    The zero-point sensitivity of such a device has a very broad peak, so the actual parameters do not have to correspond closely to the optimal ones.
