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.
Claims20
A laser scanning microscopy 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) including a plurality of transducers electrically coupled in parallel with first and second radio frequency (RF) inputs for controlling the direction and intensity of the laser beam into two different paths depending on the first and second RF inputs.

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 and a plurality of transducers electrically coupled in parallel and bonded to a crystal using an epoxy with first and second inputs that determine two different laser beam paths;
- 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.
