Non-contact friction ridge capture device

A non-contact friction ridge capture device comprising:

• a device housing, the device housing including an electronics compartment having an open side onto which a user can present the user's hand;
• the device further comprising a camera disposed in the electronics compartment for capturing an image of at least one friction ridge surface on the user's hand, wherein the camera comprises a global reset release shutter (GRRS) for capturing the image;
• a light source disposed in the electronics compartment, the light source emitting light in the direction of the open side, wherein the peak wavelength of emitted light is in the range of 440 to 570 nanometers (nm);
• and
• a light guide comprising a polycarbonate tube lined with an enhanced specular reflector (ESR) film to direct the emitted light toward the open side in a uniform manner;
• wherein the user's hand is not required to contact the device when the camera captures the image of at least one friction ridge surface on a user's hand;
• wherein the device housing further comprises an illumination shield connected to the electronics compartment such as to provide an opening between the illumination shield configured such that the user's hand can be inserted between the illumination shield and the electronics compartment, the illumination shield including a light absorbing material and reduces blurring that may occur in an image captured using the global reset release shutter due to the effects of ambient light.
