自适应光学系统AO System

AO 系统概要

光傲科技提供荷兰OKO公司全套闭环自适应光学系统，用于实时修正光学系统的像差，产生精准的波面，应用领域包括科学仪器、天文光学、眼科光学、激光光学、光学对心系统等

OKO公司提供的闭环自适应光学系统主要有2种

• 基于OKO公司薄膜变形镜(MMDM,最高可达79控制通道）的自适应光学系统
• 基于OKO公司压电变形镜(PDM,有19,37,79,109通知通道）的自适应光学系统

Aberration correction is possible in circular, rectangular, annular, elliptic and annular elliptic apertures. The feedback frame rates of 30 ... 1500 fps, depending on the camera and computer used, are sufficient for correction of aberrations caused by the atmospheric turbulence.

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, mode filtering, operations with the background, etc .

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 PDM

AO systems with PDM are based on our technology of piezoelectric deformable mirrors (PDM). These mirrors can compensate large optical aberrations in a frequency range up to 1 kHz. Currently we fabricate PDM with 19, 37, 79 and 109 channels with apertures of 30mm and 50mm. Since these mirrors can produce large local responses, they are efficient for the correction of aberrations of the human eye, laser systems and other demanding applications.

Complete systems are always 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 running FrontSurfer WF reconstruction and contrrol 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.
