3D Vision based on MALS™ (All-In-Focus, Multi-Focus, Vari-Focus)

Common optical system consists of an image sensor that recognizes an image via an multiple of lenses. It has a structure in which focus has been changing whenever varying the distance between Lenses and image sensor drived by the electric motor." Variable focus is physically drived so that variable-focus speed is slow and current consumption is high. Therefore, it is not permanent. The technology of MALS(TM) stands for Micro Mirror Array Lens System. It is reflective-type mirror lens manufactured by semiconductor WAFER. The feature of MALS(TM) is as follows. • Ultra High Focusing Speed up to 12000Hz • Long Term Reliability more than 1 billion operating cycle • Ultra Small Power Consumption less than 1mA • Shock Resistance more than 5000G • Operating Temperature Range: -30 ~ 100 deg.C • Single Camera Based 3D Camera • Volumetrically 25% Smaller than Current Technology Based Module • Real-Time Multi Focusing • Applicable to Volumetric 3D DISPLAY , Compact Auto Focus and 3D camera module Each mirror is drived to the desired position according to the previously designed optical data. It has repeatability of 20 nanoscale and almost permanent life time. In addition, focus is variable without going through the intermediate step, due to ultra fast changing of lens shapes, and multiple focuses as well as all focuses are simultaneously possible due to the speed of 12000 variable times per second In addition, it is exact, repeated variable at a high speed so that it enable to measure exact depth data and to extract 3D data through 3D depth map. In the field of Vision Inspection, MALS demonstrates its outstanding ability. If there is a step or multilayer for a target object at the general optical inspection, it is difficult to capture accurately focused images. Also if you use ACTUATORS such as STEP MOTOR and PIEZO, it will cause serious problems in the driving speed and repeatability. However, an optical system using a MALS is able to obtain high-quality vision images regardless of the height of the step. Following Video is a WISESCOPE(TM) 1.3X Demo Video. WISESCOPE(TM) mainly have a All-in-Focus function(totally 320 focus step), Depth Sensing function, Multi Focus function. Firstly, you can see the All-in-Focus & Depth Sensing demonstration Video. Circuit sample Inspection Video. Although phisically shift the sample(Top,Down,Left,Right), still can get the All-in focus Video. Slow mode & Very slow mode is included. It enables to measure exact depth data and to extract 3D data through 3D depth map for its exactly repeated variable operation at a high speed so that. Following’s are PCB sample demonstration video at the same way. Next, you can see the Multi focus demonstration video. Focusing step changing with scroll-bar manually. Set the ROI(region of interest) by dragging mouse pointer. Although manually change the focus, the focus of marking area is maintained.
