1. A hyperspectral imaging device comprising:
a code generator configured to generate a code signal including first code information and second code information which are orthogonal to each other;
a light transmitter configured to receive the code signal and to generate output light including first modulated light modulated based on the first code information and second modulated light modulated based on the second code information; and
a receiver configured to receive reflected light from which the output light is reflected from a sample, and to obtain a hyperspectral image based on the reflected light and the code signal, and
wherein the first modulated light has a first wavelength band and the second modulated light has a second wavelength band different from the first wavelength band
wherein the transmitter includes:
a light source controller configured to receive the code signal and to generate a first control signal based on the first code information and a second control signal based on the second code information;
a first light source configured to generate the first modulated light based on the first control signal; and
a second light source configured to generate the second modulated light based on the second control signal,
wherein the first light source is configured to generate the first modulated light by adjusting a time for generating light based on the first code information, and wherein the second light source is configured to generate the second modulated light by adjusting a time for generating light based on the second code information,
wherein a number of bits in the first and second code information is increased for a static image with high sharpness and decreased for real-time images.
