AO 系統(tǒng)概要

光傲科技提供荷蘭OKO公司全套閉環(huán)自適應(yīng)光學(xué)系統(tǒng)，用于實(shí)時(shí)修正光學(xué)系統(tǒng)的像差，產(chǎn)生精準(zhǔn)的波面，應(yīng)用領(lǐng)域包括科學(xué)儀器、天文光學(xué)、眼科光學(xué)、激光光學(xué)、光學(xué)對(duì)心系統(tǒng)等

OKO公司提供的閉環(huán)自適應(yīng)光學(xué)系統(tǒng)主要有2種

• 基于OKO公司薄膜變形鏡(MMDM，**可達(dá)79控制通道）的自適應(yīng)光學(xué)系統(tǒng)
• 基于OKO公司壓電變形鏡(PDM，有19，37，79，109通知通道）的自適應(yīng)光學(xué)系統(tǒng)

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.
