Methodology of camera spectral response measurement
Melich, Radek; Václavík, Jan; Žídek, Karel
2016 - English
Spectral response of the camera will be measured using monochromator in conjunction with an integration sphere. Camera without objective will be placed in one port of the integrating sphere and light beam from monochromator will be fed into perpendicular port. Sensor of the camera sensor will be therefore uniformly illuminated by diffused light from monochromator. Proposed FWHM of the monochromator is 15 nm as a trade-off between light intensity provided by monochromator and deformation of spectral characteristic (Picture XY). Diameter of the integrating sphere has to be larger than 100 mm to ensure uniform illumination over sensor area.

Device calibration.
Melich, Radek; Václavík, Jan; Žídek, Karel
2016 - English
The device has to be calibrated in absolute terms for its brightness response. This will be facilitated by a combination of an integrating sphere and collimating objective. The emitted total light intensity will be controlled by a reference photodiode inside the integrating sphere.

Selection process of an observation objective with respect to minimal glare level
Melich, Radek; Václavík, Jan; Žídek, Karel
2016 - English
An observation objective (OO) that will image the projection screen on the camera detector is necessary to choose in a such a way that its glare performance is traced. This objective feature is not documented by an objective supplier, therefore we design a procedure that enable us to relatively compare the objective between each other.
