Abstract
A laser scanning microscopy system includes a laser whose beam is modified by an acousto-optic deflector that includes an optical element having a surface with one or more steps formed thereon; a conductive layer formed on the surface with the steps; one or more crystals secured to each step; and electrodes positioned on each surface of each crystal.
Claims19
A system comprising:
- a laser for providing a light source;
- a scanning system for scanning the laser beam across a sample;
- a detector for detecting emitted light from the sample;
- and
- a phased array acousto-optic deflector (AOD) for controlling the direction and intensity of the laser beam, wherein the AOD includes an optical element having a surface with one or more steps formed thereon, a conductive layer formed on the surface with the steps, and one or more crystals secured to each step.

A method to perform microscopy, comprising:
- providing a light source with a laser;
- controlling the direction and intensity of the laser beam using a phased array AOD with one or more steps, a conductive layer formed on the surface with the steps, and one or more crystals secured to each step;
- scanning the laser beam across a sample;
- detecting emitted light from the sample to generate an image of the sample;
- applying the laser beam to an optical element having one or more steps each with a predetermined height and one or more crystals or transducers on the one or more steps;
- impedance matching the electrical input of the transducers to a predetermined impedance load;
- providing an electrical input to deflect the laser at the two or more frequencies;
- and
- generating a sound field in the optical element to deflect a laser beam based on two or more frequencies.
