StillI: Enhanced imaging in turbulent conditions
OKO extends the capabilities of modern imaging systems by introducing purely software-based system for image stabilization, object tracking, frame integration and multi-frame deconvolution. It offers an almost real time enhanced imaging through turbulent and wavy media. The system works with live video sequences fed via DirectShow (webcam) interface, or from a CMOS or CCD camera. To get the impression, please watch the recordings below, better seen in a full-frame mode. Feel free to contact us with any technical question, or for an offer. The basic configuration of the system is available from stock.
Direct control of Zernike modes using piezo and membrane DM
Direct control of Zernike modes is beneficial in feedforward control algorithms, and in optimization-based adaptive optics, such as laser intracavity AO, adaptive image sharpness control, smart PSF control in microscopy, optimal imaging through turbulence with stochastic optimization, etc. In all these cases the dynamic control of Zernike modes provides for very quick quasi-optimal convergence to the maximum value of the target function.
Here we show a 15 mm 37-channel OKO Micromachined Membrane Deformable Mirror (MMDM) and 30 mm 37-channel Piezoelectric Deformable Mirror (PDM) operated by Zernike polynomials in feedforward control mode. No wavefront sensor is used during the mirror operation. Both mirrors are controlled by our free MiZer software.

Software application to directly control OKO deformable mirrors with Zernike polynomials.
Adaptive Optics Breadboard
In this article, we show a breadboard setup of a complete closed-loop adaptive optical system that can be used for educational purposes or as a test setup for deformalbe mirrors, wavefront sensors and control software.
Deformable mirror with integrated tip-tilt
We have just introduced a new membrane deformable mirror integrated with a piezoelectrical tip-tilt stage. The mirror has 15 mm diameter and 17 actuators, with the geometry optimized for the correction of low-order aberrations. The integrated tip-tilt stage allows to avoid the double use of the pupil-conjugated plane and to build compact and simple adaptive optical systems. For more detail, please read the mirror description and our recent technical article.
