Design of an ellipsoidal mirror assisted oblique plane microscopy

open access: yesFrontiers in Physics, 2022
Using one objective for excitation and detection simultaneously, oblique plane microscopy (OPM) provides a mounting-friendly approach for optical sectioning. Unfortunately, the original OPM has three major defects: the mechanical constraints when placing

A New Model of the Speed of Light Reflected from a Moving Mirror

open access: yes, 2023
The classical emission (ballistic) theory of light predicted that the speed of light reflected from a moving mirror is c + 2v , where v is a component of the mirror velocity. In 1913, A.
