Background:

  • Traditional multiphoton multifocal microscopy (MMM) techniques often involve complex setups.
  • Existing methods utilize galvo scanners, microlens arrays, rotating disks, or beam splitters with asynchronous scanning mirrors.

Purpose of the Study:

  • To develop a more compact and efficient multiphoton multifocal microscopy (MMM) system.
  • To improve the fidelity and speed of live-cell imaging.

Main Methods:

  • A high-diffraction-efficiency diffractive-optic element was employed.
  • This element generates a uniform intensity multiple-spot grid.

Main Results:

  • A neat and compact multiphoton multifocal microscopy (MMM) system was successfully demonstrated.
