Claim Text:
1. A testing system comprising: a first support structure; a second support structure; at least one display; a vibration loading system (VLS) operable to generate vibrational loading, said VLS is supported by said first support structure, wherein said VLS further comprises a vibration isolation structure adapted to enable lateral movement of a VLS support section and attenuate or reduce vibration transmitted from said VLS to said first support structure; a VLS control system section comprising a first recording medium section configured to store a first plurality of non-transitory machine readable instruction configured to control said VLS based on a first plurality of user inputs comprising one or more frequency of vibration associated with one or more VLS table vibration instances specified in cycles of said VLS per unit of time, a dwell time for each said one or more frequency, and an amplitude of acceleration or position at each said one or more said one or more frequency; a mounting structure adapted to receive a System Under Test (SUT) comprising an optical element and imaging system configured to receive light through or reflected off said optical element, said mounting structure couples the SUT with the VLS support structure, wherein said mounting structure includes a first and second clamp section each having a recessed section facing the SUT configured to receive an adjustable focus ring section of said optical element so as to apply clamping force on optical element areas adjacent to said focus ring while said optical element is clamped within said mounting structure; a first acceleration sensor coupled with the VLS configured to provide VLS acceleration data; a first Illumination Target System (ITS) comprising a light source configured to generate and pass ITS light through said optical element, said first ITS is supported by the second support structure, said second support structure is spaced apart from said first support structure, wherein said first ITS further comprises a distortion target comprising a transparent glass with a fixed spacing grid or pattern of light absorbing or opaque structures; a Test Control System (TCS) comprising a signal buffer configured to receive said VLS acceleration data, a band pass filter receiving inputs from said signal buffer, and amplifier receiving inputs from said band pass filter, and a zero crossing detector receiving inputs from said amplifier that outputs a trigger signal output when said amplifier signal is above or below a first voltage threshold, said TCS further comprising a light source driver generating a power signal to said ITS to power and control said light source, wherein said first acceleration sensor provides said VLS acceleration data; an Electro-Optics Control Computer (EEOC) section comprising a data acquisition section coupled to said signal buffer and said zero crossing detector, said EEOC further comprising a second recording medium section configured to store a second plurality of non-transitory machine readable instructions configured for controlling said EEOC section, said TCS, and said imaging system based on said trigger signal output from said zero crossing detector, said signal buffer output receiving said acceleration data, one or more frequency of vibration, said dwell time, and a second plurality of user inputs, said second plurality of user inputs comprising one or more phase delays of vibration cycle to ITS pulse occurrence defining a phase delay between vibration cycle start and an activation of said ITS light output, a pulse width defining a duration of operation for said ITS light output, a frame rate for image capture from said imaging system, and a black level for defining a low light pixel signal value added to all said imaging system's pixel output to adjust for pixel outputs below a first signal intensity measurement level to avoid clipping said pixel outputs below said first signal intensity measurement level and zero output from one or more of said imaging system's pixels, wherein said EEOC synchronizes said light source driver with VLS position based on said zero crossing detector output, wherein said EEOC section further configured for recording a plurality of test data from said imaging system; and a processing section configured for real-time or post-processed optical characterization of said test data comprising images from each said image capture, generating a first plurality of analyses outputs on said images comprising generating a first distortion analysis output to create a distortion mapping result (DMR) analytical output comprising a percentage difference or displacement from imaged said grid or pattern of light absorbing or opaque structures compared to positions of said grid or pattern of light absorbing or opaque structures, storing said DMR analytical output, creating a second distortion analysis output comprising said DMR analytical output shown in a graph on said display as a function of vibration frequency, creating a third distortion analysis output comprising a comparison of said DMR analytical output with a predetermined distortion or warping tolerance in predetermined applications comprising a measurement of a predetermined human capacity for distinguishing said images of objects viewed through said SUT at a predetermined distance or a predetermined resolution value.
