Apparatus and related methods are provided for evaluating effectiveness of a visual augmentation system (VAS), such as night vision goggles (NVGs). The apparatus and methods illustratively measure the response time of the visual augmentation system (VAS) as a function of targeting detection, engagement, and scan angle.

Visual augmentation system effectiveness measurement apparatus and methods

Systems and related methods are provided to perform optical characterization of system under tests (SUT), including one or more optical elements (OE), for various purposes including evaluation of optical resolution needed to distinguish image elements, blur, line of sight jitter, and/or pointing stability. Various testing systems and methods are provided including an embodiment having a vibration loading system (VLS), a first acceleration sensor coupled with the VLS, and a mounting structure adapted to receive the SUT. An illumination target system (ITS) emits light that passes through the SUT OE's lens and is captured by the SUT's imaging system. A light control system controls the ITS based on a plurality of activation commands and a Test Control System (TCS). The TCS receives ITS input through the SUT that is synchronized with acceleration sensor data (e.g. phase of VLS position) and analyzed via real-time or post-processing.

Characterization and evaluation of optical elements under vibrational loading

Methods and systems are provided for identifying entities and communicating using lightweight and wearable free space optical systems. A variety of optical and electronic elements are used to enable communications and identification in an environment where identification and communication must be accomplished to address a variety of constraints. Such constraints can include frequency congested environments or environments in which communication should be done using non radio frequency (RF) systems. Embodiments include converting data into optical signals that are transmitted using a laser which are received by optical receivers and converted into audio output.
