1-13. DESCRIPTION OF TEST CONSOLE TEST BENCH 2A2 (cont)
(a) The relay bracket assembly 2A2A3A1 consists of three relays K1 thru K3,
a connector, and a mounting bracket.
It provides relay control of signals to the
collimator/image lamp, and uniformity lamp.
(c) The collimator assembly is located between the front panel and the
light shield assembly.
It directs the light source to the EO aperture.
(d) The amplifier-detector assembly 2A2A3A4 consists of integrated circuits,
fixed resistors, variable resistors, terminals, and an electrical connector, mounted
on a printed wiring board.
(e) Integrator sensor 2A2A3A3 is a photo sensitive diode mounted atop the
(g) Light shield assembly 2A2A3A2 consists of a lamp retainer, photo-
quartzline lamp, and light sensor.
(h) Integrating sphere 2A2A3A5 is a globe shaped chamber housing three
It provides uniform light outputted at the shading port.
(i) The cable harness assembly 2A2A3W1 provides all of the electrical
requirements for operating the OSG.
It consists of connectors J1 thru J2 and P1 thru
(j) Two fixed mirror assemblies are mounted on the assembly. These
assemblies are in line with the TV target source and operate in conjunction with the
optical relay assembly to direct the target image to the TV camera.
(k) The optical relay assembly is located between the fixed mirrors and
Its purpose is to reduce by one half the size of the incoming TV target
(l) The lens target assembly is located between the optical filter and fixed
It provides the target that is optically directed to the TV
