[argyllcms] Re: DIY reflective spectro

I just considered some points for a colorimeter:

1.) Light sources:
LEDs are quite stable on their wavelength/intensity

2.) Calibration:
How about a set of laser diodes with several wavelengths as reference?

3.) Sensors:
There are sensors for temperature or humidity from TI which provide the current
value as a 9bit-code and are CALIBRATED by MANUFACTURER.

Are there similar sensors for color and brightness (or are there sensors 
providing
a freqency dependent on the value which can be interpreted as bitstream)?

4.) Laser interference:
Is it possible to interpret the interferences of a laser as colour or brightness
(like a laser metre does with distance)?
