    • Techniques are disclosed for improving the quantum efficiency of photocathode devices. The techniques allow for an increase in the optical thickness of the photocathode device, while simultaneously allowing for an increase in the probability of electron escape into the vacuum of the device. The techniques are particularly useful in detector and imaging. In one embodiment, a photocathode device is provided that has an array of corner cubes fabricated in a surface of the photocathode. The corner cube array is made of the same material as the photocathode layer. The device may be, for example, a detector or image intensifier that operates in the UV, visible, and IR light spectrums, and may further include a gain medium, anode, and readout device. Techniques for forming the device are also provided.

    • A transceiver system allows for simultaneous operation of transmit and receive modes, even in shared path configurations, by temporarily making the receiver insensitive to transmitter energy and by modifying standard readout technology to rapidly dissipate any transmitter energy deposited onto the receiver's detector elements. The entirely electronic technique alerts the receiver to the imminent emission of each transmitter pulse. This alert opens a gate voltage switch in the readout and prevents energy that is present on the detector from being passed to the readout integrator. As soon as the transmitter pulse has passed and any charges it generated on the detector have been dissipated, the switch is automatically closed and the receiver is again fully active. Since this on/off switching happens automatically and rapidly it can operate independently from, and have very little impact on the receiver. Furthermore, it levies absolutely no limitations whatsoever on the operation of the transmitter.
    • 收发器系统即使在共享路径配置中也允许通过暂时使接收机对发射机能量不敏感并通过修改标准读出技术来快速耗散沉积在接收机的检测器元件上的任何发射机能量来同时操作发射和接收模式。 完全电子技术可以使接收器发出每个发射器脉冲的即将发射。 该警报在读数中打开门电压开关,并防止存在于检测器上的能量传递到读出积分器。 一旦发射机脉冲通过并且其在检测器上产生的任何电荷已经消散,则开关自动关闭,并且接收器再次完全有效。 由于该开/关切换自动快速地发生,它可以独立于接收器而且对接收器的影响非常小。 此外,它对发射机的操作绝对没有任何限制。
