A handheld device for measuring the colour properties of objects

Номер: GB0002474701A
Принадлежит:

A handheld device is disclosed for measuring the colour properties of objects. An internal CPU 6 via control signals 7 causes emissive light source 1 (a LCD and/or one or more LEDs) to generate a sequence of specified spectra. The emitted light is transmitted via light guide 3 and is incident on object 5 to be measured. Reflected or transmitted light from the object is transmitted via light guide 4 to an internal digital camera 2 such as a CCD camera. The data 8 is passed to internal CPU 6 where calculations are performed on the measurements. Optionally the CPU 6 passes the data via internet connection 9 to an external CPU 10 to enable further calculations to be performed. The design allows for use of an existing handheld device such as a mobile phone to be used as a convenient way of providing the included LCD, camera, CPU and optional internet connection.

An accessory, such as drawer 41, is configured to be mounted on the spectrometer and has a surface, e.g. window 412, configured to receive the sample. The spectrometer arrangement can operate in two configurations. In one, the laser illuminates the sample before reaching the level of the e.g. window surface, for example figure 8 with a petri dish facing towards the spectrometer and no material between the spectrometer and sample. Alternatively, the laser reaches the surface level before illuminating the sample, for instance figure 9 where the petri dish faces away from the spectrometer and the sample location is known at the base of the petri dish, allowing a fixed focus operation. Also disclosed is a Raman spectrometer having an interlock mechanism enabling laser operation when an accessory is mounted.
