my question is what are the electro optics and DSP that they maybe can do in this device? How this device work?
Don't know where this came from but based on what I see:
The device has a single imaging device (camera), and a lens array (many lenses).
With one camera and many lenses, you need a way to switch lenses. The electro-optics would be the method of moving the lenses, or otherwise altering the light path so that the light hitting the camera passes through different lenses.
The DSP (digital signal processor) is the computer that reads the data from the camera electronics and uses math to find features in the scene.
If you are asking if we can tell you how to make it work, the answer is "no". But I might be willing to buy it from you for $10.
