Frequently Asked Questions
1. How does uncooled focal plane array microbolometer work?
Using the principle of infrared radiant thermal effect, the
uncooled infrared detector converts infrared radiation energy into
heat energy with infrared absorption material, increasing the
temperature of the sensitive material. This causes specific
physical parameters of the sensitive material to change
accordingly, converting into electrical signals or visible light
signals through designed conversion mechanisms to enable object
detection.
2. What's the advantage of uncooled VOx microbolometer?
Uncooled infrared focal plane detectors operate at room temperature
without requiring an Integrated Dewar Cooler Assembly (IDCA)
device. They offer advantages including fast startup, low power
consumption, small size, light weight, long lifespan, and low cost.
While their sensitivity may not match cooled infrared detectors,
years of development have made their cost-performance ratio
significantly better than cooled detectors, offering broader
application prospects.
