The wide-field spectroscopic survey telescope (WST) is proposed to become the next large optical/near infrared facility for European Southern Observatory (ESO) once Extremely Large Telescope (ELT) has operational. While latter optimized unprecedented sensitivity and adaptive-optics assisted image quality over a small field-of-view, WST addresses need volumes in spectroscopy with light-collecting power of 10 m class telescope. Its unique layout will feature combination multi-object integral field simultaneously. For intended capacity this very number detectors needed. complexity detector systems presents challenges that are discussed focus on novel approaches innovative designs can be expected emerge anticipated 20-year timeline project.
