    Setup for insects in flight. This setup take pictures of insects inflight. An optical extra lens system is added to look for insects in focus. Only 40 usec are needed to check if there are objects in focus.

    This unit works on reflected laserlight. No more leaserbeams are needed, no more long arms to put the receivers on the top of the system. The full distance is now free between camera and insects. The unit works in full dark or even in full bright sun. Sensivity can by adjusted by mean of a simple potmeter. To work in full dark 2 to 4 extra high power leds are added. 2 of this high power leds are UV leds at 405nm. This UV light attrack some insects inflight.

    Today the first real live tests are done. This works realy nice. At this time no insects are available considering the winter periode here. Focus distance can by adjusted to every value. The focus range of the detector is very narrow. 1 to 2 mm at a distance of 700 mm form the camera. Objects of 2 mm diameter can by easily detected. Detector works also on full black insects. 4 lasers are used, 2 IR 5 mw lasers at 850 nm and 2 x 10 mw green lasers. The green lasers are only for visual position to the insects.

    All electronics are mounted into the frame. One CPLD board is used and 2 boards with an AVR controller. The information from the optical system are fast transmitted from the AVR controller to the CPLD board. An 2x16 character LCD display give the status from the system. value of the batterys, value of the high voltage for the electro magnet at 150V, sensivity of the focus detector, width of the digital filter used, value of the environment light, value of the laser return light and expired time between start camera and moment of the picture.

      Wow! Amazing gear, I can't wait to see the results :)

      This unit is really extraordinarily. Now the first live tests are done I can say that this works very very good! Because the optical detector look only at the middle of the picture the object there is always perfect infocus. No more problems with disturbed objects at the side.

      This is amazing. Recently I'd been thinking about building some electronics for my camera.. namely, a timer for shooting time lapses, and a better flash trigger for high-speed shots, but this is just way beyond that level. I'd love to try this out with my Canon MP-E 65 macro lens.

      Most benefit come from the free room between the insects and the camera now. And especially the very high speed of the detector as fast as 40usec. Of course the external shutter give still 6 msec delay between detection and picture on the D200 but i can live with this small delay.

      I was really surprised with the small focus zone and this short reaction time of the detector. The detector works on relatieve values, this mean that only the difference between environment light and laserpulses are measured. This difference is now between 3 and 50 units out the detector, the environment light change from 167 dark to 60 into full sun, but the difference from the environment light minus the laserpuls stay always near the same value. Its works like a boat on the sea undulation.

      Wow - what an amazing setup!

      Beautiful engineering, beautiful construction, and amazing performance characteristics!

      It will be great to see your insect flight photos in the Spring.

      Thank you for posting these equipment photos and the descriptions.

      Thanks DQE!
      Yes I know, it's hard to wait so long! But the temperarure here is minus 5 degree, no one insect to find outside. I expect only at the beginning of March the first insects in-flight again.

      But i hope enormous that the results will be super. This year I will spend much time into the dark, at night, to capture moths. In the daytime I want to capture now the bigger insects. This setup works also at longer focus distance compared to the preceding version.

      We're starving for Images at Front & Back...!
      Could you please add this to our shoe box...!

      Thanx!
