In the past the setup of this laser signal was always a pain. This adjustement need to be very exactly to have the max reflected signal on the microcontroller. Now the new setup make this adjustements simply. I can finetune the laser into all direction, first very coarse and then very precise into the X and Y direction. As you can see there are a lot of small parts. But this new setup give me the assurance to have always the max detection signal. This cost me 5 days of heavy works to make all this very small parts! once for the left side and once for the right side. The IR laser works at 840 nm and is pulsed 20us on and 20us off. The difference between the ambient light and the IR laserlight is processed into the AVR controller ATtiny45 into a separeted macro lens the AF60/2.8Dmicro from Nikkor. The information go to the central CPLD controller to make the decision to take a photo in focus.
