We aim at realization of medical image diagnosis by palm-size mid-infrared (LWIR: Long Wave Infrared) passive spectroscopic imager. In conventional apparatus, the actuator driven by the ultrasonic motor has two issues, low durability and high cost. Therefore, we proposed a thermal-expansion actuator to solve the problems. This actuator does not use a mechanical drive division and is controlled slowly constant driving speed. We examined the expansion machinery and the heating/cooling mechanism. Then, it was confirmed that they satisfy the required performance of working distance and driving speed.
