SBIR’s VEO-2 system provides a compact, portable, high-performance, turnkey solution for test and evaluation of IR, visible/TV, DVO, and laser rangefinder/designator UUTs.

VEO-2 features reduced mass, volume, and complexity relative to the TETS system, and may be transported in a single shipping container. The system’s reduced size maximizes ease-of-use in space-constrained areas. VEO-2 supports critical specifications for field testing, and offers comparable electro-optical performance. The VEO-2 system combines TETS functionality into a reduced number of EO modules, via leverage of numerous previous and current EO tester development programs. System control and test automation is achieved using the IR Windows™ test software and leverages TETS developed work.


The main unit consists of all VEO-2 measurement components with the exception of the laser range and receiver sensitivity measurement function (this is housed in a small separate unit that is independently mounted on the TPS fixture and is called the Laser Range and Receiver Sensitivity (LaRRS) subsystem. 

The main unit houses the following subsystems, each having their own components.

Collimator Subsystem

Collimator optics: Off axis parabolic mirror and fold mirror

Retro-reflector optics and assembly

Electro-optical subsystem

Target wheel

Sources: Visible, IR, Laser Boresight

Laser Camera

Laser Energy Probe (Joule)

Slide mechanisms that support selecting sources and camera/energy probe

Electronics Subsystem

Ethernet interface to core

Command and control electronics

Target wheel

Slide assemblies

Visible source luminance

IR source temperature

Lasers control

Temperature measurements

Laser Range Receiver Sensitivity (LaRRS) Unit

Performs range measurements

Sensitivity measurements

Autocollimation with main unit

VEO-2 Modulated Source Capability
To support TOW and TOW derivative applications, VEO-2 can incorporate the existing TETS modulated source boresight measurement requirements. This is an option not currently included in the VEO-2, but easily incorporated if desired. Modulated Source capability can be quoted by SBIR if desired.

IRWindows™4 TPS Development Environment

The VEO-2 test set can also be optimized for seamless integration with the SBIR IRWindows™ test system. IRWindows™ is an advanced software tool that automates the setup, execution, data collection and results analysis for industry standard performance testing of infrared, visible and laser sensor systems.
