LIGHT MEASUREMENT DEVICE WITH IDENTIFIABLE DETECTION ELEMENTS

摘要

A light measurement device comprising an optical sensor that includes a tunable interference filter and a detecting section detecting light passed through the tunable filter, a storing section that stores a first correlation data and a second correlation data, and a CPU that obtains amount of the light by controlling the optical sensor based on the first correlation data and a second correlation data.

1. A measurement method for a light measurement device, the measurement method comprising:
controlling a tunable interference filter based on a drive input, such that the tunable interference filter transmits a selected wavelength of a light; detecting light passed through the tunable interference filter via a plurality of detecting elements arranged in a two-dimensional array; identifying a subject detecting element from among the plurality of detecting elements based on a correlation data stored in a storing section, wherein the subject detecting element receives the light having the selected wavelength transmitted by the tunable interference filter, and the correlation data indicates a wavelength detected by each of the detecting elements for a given drive input; and determining an amount of the light detected by the subject detecting element.
