Abstract: A distance measuring apparatus includes an image sensor and an image sensor driver. The image sensor includes a photodiode, a first capacitor and a second capacitor, and a first transfer gate and a second transfer gate configured to transmit an output of the photodiode to the respective first and second capacitors. The image sensor driver is configured to complementarily drive the first transfer gate and the second transfer gate.

Abstract: Provided is an absolute position color scale disposed to represent a binary code using a first symbol, having a first width and representing a first state (“HIGH”), and a second symbol having the first width and representing a second state (“LOW”). Each of the first and second symbols is divided into two or more segments having the same structure, and the first symbol has the same shape as the second symbol, but has a color pattern different from a color pattern of the symbol.

Abstract: A thickness measuring apparatus and a thickness measuring method. The thickness measuring apparatus includes a light source outputting an extended monochromatic light with coherence; a collimating lens converting output light of the light source into incident beam of parallel ray; a beam splitter reflecting and providing the incident beam to a measurement target and transmitting first reflection light reflected on a top surface of the measurement target and second reflection light reflected on a bottom surface of the measurement target; an imaging lens disposed between the measurement target and the beam splitter with a predetermined focal distance to receive and provide the incident beam to a measurement position of the measurement target disposed on the focal distance; a camera photographing an interference fringe formed by the first and second reflection lights and outputting an interference fringe image; and a processing part.
