3D high-speed camera, laser controlled version 2012. The mechanical assembly is complete. Next task is to connect all the cables and write the software. This camera system is especially designed for capture flying insects in closeup in 3D. The IR laser signals are used for auto detection if the insects are in focus. Detection delay is superfast and only 120 us (0.12ms). The smallest size of an insect in-flight is 1 mm at 500mm from the macro lens.

2 Nikon cameras now D300+D200 but the D200 will be replaced in the future.
2 x Nikkor AF105/2.8D macro lens.
Flashes SB-800, SB-80-DX.
Flash power control via TTL on the control box.
Beamsplitter plate (50/50) size 85x60mm x1mm.
Stereo base shift 4-15mm.
2 x IR pulsed lasers at 980 nm pulsed 30us On 30 us Off.
In-flight object detection minimal 60 usec delay, normal 120 us (2 times correct level).
Detection lens for IR reflected signals AF50/1.8 Nikkor, detection delay max 120 us (0.12ms)
IR laser beam pass through the same beamsplitter (on the side) and goes via a small frontside mirror to the detector lens at 90 degree.
2 x Green lasers to see where the virtual focuspoint is located for pointing the camera at the subject.
IR laser sensitivity surface minimal 1mm x1mm at 500 mm distance from the lens.
Global controller: ATmega328p @16MHz.
IR detector Attiny26 + BPW41N photodiode built in narrow-bandpass filter.
Camera synchronization via AVR controller and 10 pins Nikon connector, shutterdelay set at 58ms (52ms if 2x D300).
Burst mode set to 3 frames/sec.
Input connection for an external control signal to capture waterfigures in 3D.
Power via 6 x AA batteries, High efficiency DC/DC converter for the laser power (3.3v 750 mA).
All PCB's single layer, so self-etching can be done.
Weight: 7.2 kg.

other sizes: small medium large original

A very impressive set up
