摘要：
An optical module (120) includes: a light source (121) configured to emit diffusion light to tracks (SA1, SA2, SI1, SI2); one light receiving array (PA2) and another light receiving array (PA1) which are arranged across the light source (121) in a width direction (R) substantially vertical to the measurement direction (C); a light receiving array (PI2) arranged between the one light receiving array (PA2) and the light source (121), and configured to receive light which is reflected at the tracks (SI2) having a first incremental pattern; and a light receiving array (PI1) arranged between the another first light receiving array (PA1) and the light source (121), and configured to receive light which is reflected at the tracks (SI1) having a second incremental pattern which pitch is longer than a pitch of the first incremental pattern.
