Optoelectronic detectors are composed with light-sensitive components known as well as photo-sensitive. Optoelectronic detectors react to:
> a variation of intensity,
> an amplitude of intensity.
HTDS proposes a full range including photodiodes (light measurement), photoresistances (luminous intensity control), pyroelectric detectors (motion detection) or thermopiles (temperature measurement).
From UV to infrared, HTDS proposed a wide range of products used in industry or on scientist or military markets.
