Multiple Photodiodes
Multiple PDs (PDM) for the mid-IR spectral range become a new component base for portable optical sensors for gases and liquids. Such PDs are miniature and highly efficient.
- Main applications:
- - Diode-Lasers spectroscopy;
- - Laser rangefinding and location systems in the eyesafe spectral range;
- - The free-space optical links;
- - Communication systems based on fluoride fibers with loss of 10–2-10–3 dB/km;
- - Environmental monitoring;
- - Medicine;
- - Remote non-contact temperature measurements;
- - Detection of the burning or explosion products.
- 2-element PDs
- 3-element PDs
- 4-element PDs
