How the damned thing works.....

Unlike other scanners, our LightPin^TM system uses no laser for sprocket hole detection. Instead, an off the shelf reflective sensor employs a simple, pin point LED light beam which is reflected off the film surface. When the passing of a sprocket hole interrupts that reflected light beam, the camera is triggered to capture a single frame of film as it passes by. The fact that we use a reflective sensor means clear edge film is captured just as easily as film with a black edge. This is because the LightPin^TM sensor is looking for the physical presence of the film and does not care about film density. Because some sprocket holes may be damaged, the positioning of the sensor is adjustable across the width of the sprocket hole. Also, the system allows the user to select which end of the sprocket hole is used to trigger the camera for best registration. Unlike other scanners, we do not use a strobe to illuminate the film. Instead, we use a constant, super bright light source with ultra high frequency pulse width modulation to ensure zero visible flicker when adjusting brightness of the image.

Please note, this is a general overview to assist potential buyers in understanding how our scanner functions. I do not offer guidance nor provide information on how to build your own system using the components listed. I'm sure you understand.
