Modular optronic test solutions

Using various optronic components available on the market, such as off-the-shelf collimators or black bodies, or components specially developed for the needs of a project, SPHEREA designs, develops and produces optronic test solutions for workshops.

MIRT bench to test infrared sensors

These testers are used to validate the optronic system during the development, integration and qualification phases.
They serve to verify the correct operation of the equipment at the end of the production line with the capability of generating all the information required to establish an equipment performance report for the end customer.
This type of test equipment can also be used to characterise, assess and calibrate optronic devices following repair work.

Optronic test bench examples

Infrared sensor tester

IR sensor test bench

The optronic equipment, an infrared sensor of a missile departure detector system, must be tested under extreme temperature conditions (from -54°C to +90°C). This wide temperature range made it necessary to design and develop an innovative thermal regulation system that made it possible to bypass the use of an environmental chamber.

Display systems tester

Head-Up Displays (HUD)

HUD tester
SPHEREA has developed this system for workshop-based testing of head-up displays (HUD), which comprises a wide-field camera that simulates the position of the pilot's eyes.
Measurements that can be taken comprise:

  • The field of view
  • Distortion, uniformity
  • Vertical and horizontal radiation patterns
  • Contrast transfer function (CTF)
  • Harmonisation performance
  • Axial stability
  • Luminance
  • Colourimetry
  • Object and location recognition
  • Detection of dead pixels
  • Recognition of shapes


Head-Mounted Displays (HMD)

HMD tester

SPHEREA has developed test means that allow adjustment of the harmonisation of Helmet Mounted Displays (HMD) by using a wide-field camera and a wide field-of-view micro-collimator (SPHEREA patent).
