    Abstract: To provide sufficient sensitivity, spectral resolution and speed of measurement for field environmental measurements in a portable spectroradiometer, a silicon photodiode receives light: (1) having a bandwidth in the range of between 2 and 15 nm (nanometers) from a pivotable concave holographic diffraction grating within the wavelength range of between 250 and 1150 nm at a scanning rate in the range of 20 to 100 nm per second; (2) having stray light of high intensity and undesired frequencies and the shorter wavelength harmonics of the selected frequency range blocked by filters; and (3) having flux of a least 10 microwatts per square meter of diffuser plate for each nanometer of bandwidth. Automatic electrical zeroing is obtained by blocking all light once at the beginning of each scan, obtaining an electrical drift-related signal and using the drift signal to ad- just the measured signal during the scan. Several different sensing interfaces can be used, including a quartz, light fiber probe having at least a 50% packing density and a cone angle of at least 24 degrees. The data and the programming storage is at least 30K bytes but the instrument uses no more than two watts of power when the instrument is not scanning.

    Abstract: An imaging section that detects the amount of light separated by a wavelength tunable interference filter to acquire a spectroscopic image (imaging device and light amount acquisition section) detects the amount of light successively separated for three wavelengths to acquire spectroscopic images for producing a combined image. A display controller causes a display section to display a combined image based on the spectroscopic images for producing the combined image. A specified position detection section identifies based on user's operation a specified position where a colorimetry result is to be outputted. The imaging section detects the amount of light successively separated for a plurality of wavelengths by the wavelength tunable interference filter to acquire spectroscopic images for colorimetry corresponding to the plurality of wavelengths. A colorimetry section measures the color in the specified position by using the amount of light obtained from each of the spectroscopic images for colorimetry.
