Flexible Optical BV supplies complete closed-loop adaptive optical systems for real-time correction of optical aberrations and generation of precision wavefronts. Click here to download a short video in DIVX format, illustrating typical performance of our AO systems.
Applications include scientific instrumentation, astronomy, ophthalmology, laser optics and optical alignment systems. Click here for published work based on our mirrors.
We supply closed-loop AO systems based on Micromachined Membrane Deformable Mirrors (MMDM) with up to 79 channels and Piezoelectric Deformable Mirrors (PDM) with 19 and 37 channels.
Real-time AO phase control is realized by our FrontSurfer Hartmann-Shack WF sensor, offering a wide variety of control options including SVD eigenmode analysis and mode filtering. The speed of control depends on the camera and computer, usually up to 30 frames per second is achieved with standard, moderately priced camera and a laptop computer.
We can also supply deformable mirror systems with linear 19 and 38-ch MMDM and 20-ch PDM for ultrafast pulse shaping. These application-specific systems should be controlled by a customer-made feedback sensors and software.

AO systems with MMDM
AO systems with MMDM are based on our technology of Micromacined Membrane Deformable Mirrors. These mirrors are inexpensive and fast. They feature zero hysteresis and can work in a frequency range of up to 1kHz. Currently we fabricate 15mm MMDM with 19 and 37 channels, 30mm MMDM with 59channels and 40mm MMDM with 79 channels. Parameters of these mirrors are naturally matched to the parameters of atmospheric turbulence, therefore they produce best results when used for correction of turbulence.
Complete systems are usually tailored to the needs of the customer. A basic system would include a deformable mirror, one or more HV amplifier units, USB or PCI DAC controllers, CMOS firewire camera with a microlens raster, and a control computer.
AO systems with piezoelectric mirrors
AO systems with MMDM are based on our technology of piezoelectric deformable mirrors (PDM). These mirrors can compensate lrge optical aberrations in a wide frequency range - up to several kHz. Currently we fabricate 30mm PDM with 19 and 37 channels. Parameters of these mirrors are naturally matched to the parameters of the human eye, therefore they produce best results when used to correct the aberrations of the human eye.
