1. An optical device, comprising:
a time-of-flight (TOF) sensor array;
a photon conversion thin film disposed above the time-of-flight sensor array;
a light source which emits light with a first wavelength towards the photon conversion thin film to be converted into light with a second wavelength received by the time-of-flight sensor array, wherein the second wavelength is longer than the first wavelength; and
an optical component group disposed on the time-of-flight sensor array, wherein the optical component group comprises a pinhole-type collimator and a filter, and the filter comprises a longpass (LP) filter or a narrow bandpass (NBP) filter.
