1. A spectrometer comprising:
a detector comprising a plurality of pixels configured to receive light;
an optical mask disposed in an optical path of the light that travels to the detector and comprising a plurality of light transmitting portions and a plurality of light blocking portions which are arranged alternately; and
a driver disposed on two opposing sides of the optical mask to change a position of the optical mask or disposed on two opposing sides of the detector to change a position of the detector, and configured to change a light incident area of each of the plurality of pixels to receive the light incident on the plurality of light transmitting portions of the optical mask,
wherein the driver comprises at least one of an actuator, a coil, a magnet, and a Hall sensor,
wherein the plurality of light transmitting portions and the plurality of light blocking portions comprises a plurality of pairs of a light transmitting portion and a light blocking portion, and
wherein each of the plurality of pairs of the light transmitting portion and the light blocking portion is arranged to correspond to each of the plurality of pixels of the detector in a one-to-one correspondence.
