An FPGA based Frequency Synthesiser for Acousto-Optic Lens Control

چکیده
There is an increasing interest in the application of two photon microscopy in biology research. Current two-photon microscopes, which use galvanometer mirrors to steer the laser beam and build up an image, are too slow to monitor many fast spatially distributed physiological processes, such as neural activity. This paper describes the development of a system capable of generating the necessary signals to drive the four Acousto-Optic Deflectors (AODs), according to a host computer’s requests. The system will lead to the development of an application-specific, high-performance Acousto-Optic Lens Control System (AOLCS) capable of arbitrary 3D scanning and compensate for inherent aberration of the optical systems as well as tissue induced aberrations, and revolutionise neural activity imaging.

Dynamic wavefront shaping with an acousto-optic lens for laser scanning microscopy.
Acousto-optic deflectors (AODs) arranged in series and driven with linearly chirped frequencies can rapidly focus and tilt optical wavefronts, enabling high-speed 3D random access microscopy. Non-linearly chirped acoustic drive frequencies can also be used to shape the optical wavefront allowing a range of higher-order aberrations to be generated. However, to date, wavefront shaping with AODs h...
متن کاملVariable optical attenuator using double acousto-optic modulator
A novel variable optical attenuator device is proposed and some of the potential application is pointed out. It relies on a double acousto optic modulator set up and allows one to attain dynamic range as high as 60 dB. Such feature steams out of the well known modeling of acousto optic devices, mostly based on the coupled wave analysis. Furthermore, is shown that the proposed device may exhibit...
متن کاملAcousto-Optic Tunable Filters Spectrally Modulate Light
The development of opt electronic technology in the past two decades has intensified research on devices that control and manipulate optical radiation. Acousto-optic devices are based on acousto-optic effects in which the optical medium is altered by the presence of ultrasound. Examples of acousto-optic devices include optical modulators, deflectors, scanners, Q-switches, isolators, and frequen...
متن کاملDifferent Plastic Materials Based Acousto-optic Modulators (AOMs) Design Considerations for Fast Switching Applications
An acousto-optic modulator (AOM) allows to diffract a laser beam going through a crystal from the incidence angle (order 0) to another angle (order 1). The diffracted beam intensity depends on the radio frequency (RF) power applied to the device while the output angle depends on the material but is also proportional to the laser wavelength and to the RF drive frequency. When only intensity modu...
متن کاملShaping of ultrashort optical pulses by using an integrated acousto-optic tunable filter.
Reshaping of ultrashort optical pulses at 1.53 ,um by using an integrated acousto-optic tunable filter is reported. Control of the optical pulse shape is accomplished by adjusting the different radio-frequency electrical signals driving the acousto-optic filter. This is to our knowledge the first demonstration of ultrashort pulse shaping using an integrated-optic device and establishes a new ap...
