Abstract
Provided is an optical system including: a first linear polarizer of a reflection type which receives linearly polarized light transmitted through a sample; and a switching unit which controls a polarization direction of the first linear polarizer, to switch between causing the linearly polarized light received by the first linear polarizer to be transmitted and reflected, where the number of times that light transmitted through the first linear polarizer is transmitted through the sample before reaching an optical receiver is different from the number of times that light reflected by the first linear polarizer is transmitted through the sample before reaching the optical receiver.
