Abstract Introduction Fiber optic sensors for temperature and pressure using the optical system based on the Mach-Zehnder interferometer have been proposed by several workers. In order to eliminate the e#ect of noise in the reference fiber of two single-mode fibers, several methods which use only one fiber have been proposed [1], [2]. However, in these methods the special birefringent fiber is required. Instead of using such special fibers, a sensor which is constructed using a conventional multimode optical fiber has been proposed by the author[3]. In this proposed method, two modes in a multimode fiber are excited by the mode-division multiplex [4] using a computer-generated hologram [5]. In the previous report [3], a temperature change was measured by the interference between two modes. However, the theoretical analysis of the interference was inadequate in the report. In this letter, we intend to present a theoretical analysis to describe the interference phenomena by a conventio
