A passive /
active infrared imaging
system apparatus for mounting on a head / helmet includes a passive
infrared camera Head Pack having a removable
narrow band filter cover, an objective lens, a
beam splitter, an uncooled focal plane array (UFPA)
package, an interface board, and a display unit such a
liquid crystal display (LCD), with forward / back, up / down, and tilt adjustment functions fitting any
mask, mounted in the front of said head / helmet for converting
infrared light images into electronic signals. An
electronic unit coupled between the UFPA of the
infrared camera and the display unit, includes a controller for
processing video signals from the infrared camera and supplying them to the display unit. The
electronic circuit includes a
wireless video & audio
transceiver, a piezoelectric
microphone, a voice controller, and a neural
network pattern recognition
chip. The display unit (such as LCD)] is inside the head pack and mounted on the head / helmet for converting electronic signals into visible light images, so that it is in front of eyes of a user, so that the user can directly view an external scene without blocking his
normal vision, if the
optical axis of the display unit is aligned with the
optical axis of the objective lens, the
system parallax is eliminated. A
Battery Pack having a video controller board and battery is mounted on the rear of the head / helmet so that it gives the
video output and power to the infrared
system. An eye-safe
near infrared laser diode with corresponding optical and electronic attachments mounted on the head / helmet illuminates targets to get images through same passive infrared system.
