Light-to-Frequency description

Light-to-Frequency (LTF) sensors convert measurements of light intensity to a digital form for direct interfacing to a microcontroller. The output of the device is a square wave or pulse stream the frequency of which is linearly proportional to the light intensity. LTF converters are designed for applications such as ambient light measurement, light absorption/reflection in products such as white goods, photographic equipment, colorimetry, chemical analyzers and display contrast controls. They may be used in any system that requires a wide dynamic range, and/or high resolution digital measurement of light intensity.
