Abstract: An ultrasound emitter launches an ultrasonic signal into a diffuse medium such as tissue. The diffuse medium is illuminated with an infrared illumination signal. activating an ultrasound emitter to launch an ultrasonic signal into a diffuse medium. An infrared reference beam is interfered with an infrared exit signal having an infrared wavelength that is the same as the infrared illumination signal. An infrared image is captured of the interference of the infrared reference beam with the infrared exit signal.

Abstract: A system or a device for imaging includes an infrared light source, an optical structure, and a sensor. The sensor may include an image pixel array. The infrared light generates an infrared illumination signal for illuminating a diffuse medium such as tissue. An optical structure is configured to facilitate an interference of an infrared reference beam and an infrared exit signal. The infrared reference beam has a same infrared wavelength as the infrared illumination signal. The image pixel array is configured to capture holographic infrared images of the interference of the infrared reference beam and the infrared exit signal.

Abstract: A self-guiding cover assembly for a vacuum electron device (VED) enclosure has a cover, a pair of guide plates, and a pair of guide elements. The cover has a top, a sidewall, an inside and an outside, and at least one electrical connector disposed on the inside of the cover for mating with a VED. The pair of guide plates is disposed on opposite sides of the outside of the sidewall of the cover. The guide plates each have a track. The pair of guide elements is mounted on opposite sides of the outside of the sidewall of the cover. The pair of guide elements each mates with the track. The cover further comprises a breach lock mechanism for seating the VED into the VED enclosure having a base. The breach lock mechanism has guide elements mounted on the VED. A first sleeve is mounted on the base and removably receives the VED. A second sleeve is mounted on the base and removably receives the first sleeve. The second sleeve has tracks for mating with the guide elements.
