After different tests, it became clear that the effect of blocking the laser beam can be determined by processing each of the 4 channels of the PSD individually.
Our case appears to be consistent with Type 3. In previous reports as well, there were cases with an unclear outer retinal layer due to block of OCT laser by edema of the inner layer of the retina.
Under identical acquisition settings, we blocked one of the lasers at a time to verify that only one fluorophore was excited by each excitation source in ME-MPM.
A 6-mm diameter aluminum circle was placed at the center of the interface of the lens cone to block the laser.
The large error bar is due to uncertainty in the determination of the optimum laser profile when an iris is used to block the laser output from the inner cladding [ 18].
It is verified that all ionization signal disappears when blocking either of the two laser beams.
When the projectile through the detection light screen, it blocks the part light of the laser and leaves a shadow of projectile on the board.
With the tomato homogenate loaded (a small quantity of homogenate is adequate for analysis), the beam of the laser was blocked for 10 s to allow the lock-in signal to reach a zero signal level.
The validity of the proposed method is verified by comparing the FRFs of the block obtained by the laser excitation, impulse hammer, and finite element analysis.
