    Why does we use CMOS technology in the night vision goggles?

    We are night vision goggles supplier,we independently develop and sell,with R&D ability. A CMOS sensor is an electronic chip that convertsphotons to electrons for digital processing.

    The chips feature an array of minutelight-capturing cells that pick up the photons at their various wavelengths asfocused by a lens, translating them into electrons, much like a tiny solarcell. The CMOS cells are surrounded by transistors, which amplify the charge ofthe electrons by the cells, sending them across the chip by tiny wires in thechip's circuitry. A digital-to-analog converter at one corner of the devicereads the electrons and translates the differing charges of individual cellsinto pixels of various colors.

    The Fabrication Process is notcomplicated, As CMOS sensors can also integrate required electronics on thesame chip, CMOS sensors results in compact and cost effective system.

    CMOS sensors have higher speed due tothe fact that it uses active pixels and ADCs on same chip leading to lesserpropagation delays.

    CMOS sensors allow any region oreven multiple regions to be read off the sensor.

    With the integration of signalprocessing circuitry on the CMOS sensor chip, functions like auto gain control,auto exposure control etc., anti-jitter, image compression, color encoding,motion tracking, etc. can be incorporated on-chip.

    Overexposure can cause smearingaround over-exposed pixels. Smearing is caused by spilling of charge into theshift register. Due to absence of shift registers in CMOS sensors, they areimmune to this effect.
