A type of digital image sensor that converts light into electrical signals using silicon photodiodes, offering lower power consumption and faster readout speeds than CCDs. CMOS sensors allow individual pixel access and on-chip processing, making them ideal for high-speed astronomical applications and large format cameras.
A technical acronym describing the semiconductor fabrication process using complementary pairs of metal-oxide field-effect transistors. Developed in the 1960s for computer chips, 'complementary' refers to using both positive and negative charge carriers, while 'metal-oxide-semiconductor' describes the layered structure of the transistors.
